That sounds about right. An egg dropped from a low potential energy would not need much protection. The non_Newtonian fluid is somewhat thick anyway and it doesn't take much energy for it to start acting more like a solid than a liquid. Plane water in a similar bag protected an egg to 10 feet. After than, CRACK!
I came up with the same idea as an extra credit project for AP Physics C. Our second attempt we were given our choice of materials. Instead of going the standard route of slowing the descent or cushioning the fall, I believed that the cornstarch water mixture (non newtonian fluid) would distribute the force of collision equally. Instead of a plastic bag I actually used a paper cup and the egg survived a 20 ft drop!

@pistolo001 I have wondered about that as well. The next time I do this, I am going to run more tests with more eggs. I think after each drop, I will mark the egg and use another one for the next drop. Then clean the eggs up and crack them open and see what their brains are like after the fall.
why would this be any more protective of an egg than water? Fun to look at, but not sure that this has any real practical use... I would argue that a substance that hardens doesn't protect as much as one that would cusion? Not sure what formulas are involved here... So- this works any better than an egg in a bag of water?
@HungPhattt The whole thesis for this was to transfer the force of impact to the entire surface of the egg at one time. Because of the strength of the egg's shape, it is able to withstand large forces when applied in the right spots (e.g. try cracking an egg by pressing on each end at the same time.) Given enough water, it would slow the egg but this test was for a smaller amount. Water of equal vol. worked to about 11 feet. Others have done this at over 100 feet with NNF with great success.
I did try with just water and the egg only lasted to about 10 feet. This type of technology is being implemented into things such as body armor. Not only for military and police use but for down hill skiing.
gmcannon commented on here and I removed it by accident. Their comment was: Apply this to human proportions, I wonder how it would turn out.
Answer: To make this work on a person, you would need to fill them with this stuff. As it is, on impact you internal organs would not be held in place inside of your body and would become jelly. But there are other safety things being created such as body armor for skiers and soldiers. Interesting stuff.
Thanks for reposting! Interesting concept about how you'd have to "fill" a human with the fluid, but the armor also sounds like an awesome application.
yeah you can't eat the egg after as the cornflour reacts with the egg and creates a mild toxic substance. You can try it on the neighbours pet cat or dog....just feed the egg to the test subject and wait about two mins for a violent reaction of vomiting. If the egg gets ingested any further the scitters will follow....have fun kids. By the way do not test this experiement outside of a controled environment.
If you have some reference on this, please provide it. I wasn't aware that egg and corn starch created a toxic blend. Corn starch is used in cooking all of the time as a thickening agent.
@bluelagoon10023 I looked up "cornstarch and egg" but didn't find anything about poison. I did find a guy mixing it to put in his chicken. Paste 'Sweet & Sour Chicken Recipe : Mixing Cornstarch & Egg for Sweet & Sour Chicken ' into the search bar to see it.
Very true. The egg shell is what I was trying to preserver. I would bet that after a few drop the insides would make a nice scrambled egg or even an omelet. I might have to make this the preferred method of mixing eggs for omelets!
I think that the egg would survive from any height if it would say completely surrounded by the stuff. There is a group that did this experiment using a larger bag and more stuff. They dropped from 100 feet. I would think the egg and bag would be getting close to terminal velocity from not too much higher. Anyone have a 200 foot tower to use for this test? :-)
I did use corn starch and water for this one. I have also played around with white glue, Borax, and water. That turned out thicker and more like Silly Putty. It was fun to play with.
Interesting point? If my thesis was true, then the uneven surface of the landing area should not be a factor. I think it was the egg not being fully submerged in the fluid at impact that was my biggest issue.
It is a 3 way split so there hare different heights from which to drop thing. When I am cleaning house, I don't want it to be bigger. But there are times when we have a few people over when I wish it was bigger.
I did this in my high school physics class, The drop was about 50 feet, my container was a little more sophisticated and my egg survived and I won a candy bar XD
As the guy in the video said, the main issue in the last test was that the bag landed on its side. Instead of a bag, try a paper or cardboard cone, and attach tail fins or something else to stabilize it. That way, the cone's tip will be the part that hits the ground. Actually, because of the way the tip of the cone absorbs the impact, that design would succeed without non-newtonian fluid. *takes a bow, accepts Nobel prize*
The outside bag was supposed to absorb everything, so that'd pop, but the medium bag would take any left over pressure and keep the small cushioned bag safe :)
man back in grade 6 when we did the egg drop experiment, I'm not sure how common this is but the egg has to survive the fall, by what ever means necessary besides hard boiled, this would have been awesome.
Ours was done from much higher than thirty feet, around 48 or so. Likely wouldn't have done the trick unless in a much larger bag with much more non-Newtonian fluid.
if correct the non newtonian fluid turns solid when disturbed and when relaxed a fluid, well the egg is buoyant so it is on top, so when u drop the bag the turbulence causes the fluid to solid thus hold the egg in place and sponging it at the landing. and when it lands the solid is relax and at ease a fluid.
There are many thing in this world that are "not needed" yet they still exist. I understand that you don't like the bars and tone. Feel free to stop watching when they come on.
It isn't really original but you just don't see that any more. It is a through back to videos of days gone by. I must be showing my age?! Maybe I should stop it!
Its filled with something called a "Non-Newtonian Fluid". That means whenever heavy some pressure is exerted on this fluid, it temporarily solidifies and repels whatever hits it.
actually, i think the only reason the egg didn't survive ONLY on the 30 foot drop is because at that height, the egg was able to separate from the protection of the fluid inside the bag(by this i mean that objects fall at 33ft/second, and can distance from each other by any amount).
if you had done this in say, a water balloon, and only had the egg and the fluid inside(little to no air), it would have survived.
corn starch and water. I do not remember what ratio I used. That was very bad of me. I started with approximately 1/4 of the box (about 4 oz.) of cornstarch and about a half a cup of water. I hope this helps.
haha, when I did this project for school, one of the requirements was that it has to be made of materials readily available. Believe it or not I made a very successful egg dropper (tested at about 25 feet) out of about 5 sheets of paper and a couple strips of tape. Try to figure that one out :-D
i don't know how you did it. sure, mine survived a fall from a 3-story building using half a cardboard box and some school glue. i figured out the greater challenge, but if i wanted to show off my solution, i'd make a video that provided the challenge and the solution, not make a comment that talks about how cool i am. that was the, albeit lame, point. you need not point out my character flaw of annoyance upon small psychological details in others; i am aware of it.
I love the idea! I made some non-newtonian fluid for my brothers to check out a while ago, but never thought about any real-world application like that. Well, for those of us who are always dropping eggs or something. lol
Awesome! Man, I wish I'd thought of this back in elementary school when we had an eggdrop. Woulda won first place. Instead, I used water. Still worked, but not as well.
I used water up to 11 feet before it failed. More water would have given me more height but I wanted the vol. of water to be about the vol. of non-Newtonian fluid.
I did try it with water. The egg broke at 11 feet. So my drop at 22 feet was double the height.
Setting a good baseline of dropping an unprotected egg would be a good thing to establish. Then protect it with water in a bag. Ultimately, I could encase the egg in an acrylic block. That would survive quite a bit but it would be hard to use the egg after you were done.
Thus the whole reason for the experiment. If the pressure of the impact is distributed across the entire surface of the egg, we can use the freakishly strong natural structure of the egg to hold its own and stay in tact.
if the egg is completely submerged then the force is distributed around the entire shell (in theory) so becoing solid on impact is a good thing, because if it were liquid at impact the egg might hit bottom and smash the base.
Mabye if you used something like a dodecahedron as a container and suspended the egg in the non-newtonian fluid with rubber bands it would work better.
The construction of a dodecahedron would be more complex and would not provide much strength. But it would look cool! I could paint it up like a 12 sided die. I'm thinking a tube or simple box is the way to go for now.
I like the idea of using something to hold the egg within the non-Newtonian so it wouldn't float to the top. That would let the force be even distributed around the egg.
Basically, yes. At rest, the water wraps around each of the particles of corn starch and acts like a normal liquid. As you add energy, it starts to act more like a solid. If you stop applying energy, the water again works its way around the corn starch particles and acts like normal liquid. Fun stuff...
In nature you find this in the form of quick sand. In the store you find this in the form of Silly Putty.
very easy to solve with polystyrene. the box itself should be made from hard material like steel. first it would be much more stable (for many tries) and second it underlines your buffer-system as it doesnt absorb the forces from the hit. that way u should reach much higher levels.
Good idea, thank you. In my world I am trying to keep it simple. I was thinking pop can or something cheap and easy. But I do need some sort of distance-keeper to keep the egg from floating to the top.
actually u need a sphere body with distance-keepers. as a sphere is much to complicated to build + to fill with the egg and the fluid a cube is practical as well. u can fill it and close it easier. u still need distance-keepers to the borders of the cube so the egg is stuck to the middle of the room.
I was thinking of a way to thicken the mixture to help keep the egg in place without it losing it's properties as a non-newtonian fluid. After a couple of minutes I thought to mix in styrofoam pellets. I think the styrofoam would be suspended in the mixture the same way that the cornstarch is suspended in the water. It would be lighter too for experiments with a weight limit.
darn 500 char. limit! A nested non-newtonian fluid on different orders of magnitude? I think I'll give it a shot next time I have some time on my hands and a couple extra bucks burning a hole in my pocket. Let me know if you try it first.
I remember doing an egg drop way back in grade school. everyone pretty much built their vessels out of foam or wood and rubberbands. I really wish the internet was around back then so I could've done something cool like that :D
I've recently started theorizing as to what sort of practical (or entertainment) usages non-Newtonian fluids could have. I was wondering, for your experiment, assuming you used the classic cornstarch-water mix, what was your ratio of cornstarch to water?
Other people have asked me that and I didn't keep good records on this one. I kind of just added water into my cornstarch until I was happy with the mix.
If you try it, let me know how it works. I am going play some again with this in Feb. 2008. Maybe I will go that way as well? I was thinking of working on some way to keep the egg submerged. This might do both?
i think i'm going to use your idea for my physics egg drop lab. We are dropping an egg from 18 ft. Should I use the plastic bag or make a container and put the non-newtonian fluid in it?
The zip-lock bag worked like a champ at 20+ feet so why do anything else. Easy entry and exit of the egg, as well as the non-Newtonian fluid.
One thing I wish I had done on the 30 foot drop was to hold the egg at the bottom of the bag so as it was falling, it would rise up and be somewhere in the middle of the mix at impact.
well, i tried it and it broke, obviously i did it wrong but we have a weight limit of 200g, the higher the weight, the lower our score and the lower our grade, hence why i think i should use something lighter
That is too bad! How about a smaller container. How much Non-Newtonian fluid do you get at 200g? That doesn't sound like much. How about a small block of polystyrene with a small chamber in the middle. Fill it with non-Newtonian fluid and your egg.
make a drop rocket, basically put the egg in a tube filled with the fluid and build a rocket or missle shape off of that center tube. so you know it will hit the ground the way you want it to. also if you want the egg in the middle of the tube (to stop it from floating to one side) try neodymium magnets im sure that would work.
How are the magnets going to help? The rocket design is great if you want to control the impact. I didn't not want to have that type of control. I wanted the impact to be a little chaotic. If you know from where your impact force is going to come, you can design for that. If you do not know, then you have to design for any impact.
My solution is very simple. The whole idea was to distribute the force of impact over the entire surface of the egg. This should make breaking it very difficult.
for the magnets, build like a little harness for the egg for a magnet on each side and 1 opposing magnet on each end of the tube. so basically the repelling magnets on each side keep the egg in the middle.. almost like invisible springs holding it in the middle
Even a better idea. Feed the chickens a very high iron diet. Then magnetize the eggs once they are laid. Then suspend the egg in a superconductor shell. Hmm? But then how to protect that from breaking?
If I would stop dropping eggs, they would stop breaking.
Nice idea! That should work OK. What I wanted to do was to keep the egg in the middle of my chunk of fluid. To keep it fully surrounded by the stuff. Even in a full box, the very top of the egg would not be well protected. But your idea would be better than my plastic bag!
i thought of my idea and just thought that regardless if the box was ful the egg would still sink to the bottem thus the egg will break unless the box was small enough to compact the liquid and keep it in the middle... pondering on again
With the mix is used, the egg floated! That was good so it wasn't at the bottom but it was bad in that it was not completely surrounded. With your ides, you could put a small piece of foam or something to help hold the egg down a little?
The whole idea is to have the egg completely in the fluid. I would think a small piece of foam could be used to help hold it under? I think that would be worth a try.
so a non-nutonian liquid will protect an egg to a sertian degree. you have to factor in weight, hight, speed, number of items being droped, and most important wind, if any. cool!
It sort of protects the egg. By distributing the force of impact around the entire surface of the egg at one time, the natural strength of the egg shell ends up withstanding quite a drop. If that same force was to be applied to a small point on the egg shell, it would fail easily.
It is kind of the same reason people don't get killed on beds of nails. The weight of the person is distributed over many nails vs. just one.
wow thats a great application! Your video has inspired me. where i live, there was an egg dropping contest: 12 meters high above a concrete floor. the egg that reaches the ground first wins
i won with youre idea! (thank you much). i made a casing with a small plastic ball. i used rubberbands to hold the egg in the centre area of the ball. when we tested it on beforehand, it registered forces of upto 500 newton before the egg before we had yolk. so we didnt just drop it at 12 metres, we launched it!
Nice! Do you have any pictures of this? I would love to see your vehicle. So, how fast did you launch this thing at the ground and how did you launch it?
When I first saw my non-newtonian fluid video earlier, I remembered the simple physics experiment/contest we had in my class about egg dropping. ours was just made out of newspaper and tape so it broke, dropped from the third floor. then I thought about bulletproofing. I love this concept!
Thats cool... if you could stimulate the atoms present in a small space (like the inside of a car) you could use superposition to create a space in which there had ALWAYS been a non-newtonian liquid. Kind of like the car safety system in Demolition Man.
That would be a good safety device. That is kind of the whole idea around my experiment. I wanted to protect the egg. I think if it were completely surrounded by the stuff, it would have survived a much higher drop.
Undoubtedly! The practical application issues of this idea are how to surround the object in the first place... easily solvable with inanimate objects etc but the DM aspect could be tricky, unless you could get those theoretical quantum physics to work...
That is a good idea. I used the bag because it was easy and quick. I think a better container would help. I also want to do something to keep the egg surrounded by the fluid. It was too buoyant in the stuff I made and about 25% or so was uncovered. If the egg were completely surrounded, I think it would survive a much higher drop.
Cornstarch is used in cooking for thickening. You will find it used in gravy and other things. It is not the same as cornflower.
Cornstarch is a very fine power. It does not dissolve into water nor does it soak into the cornstarch.
The small particles of cornstarch are surrounded by water. That gives the mixture its fluid properties. But when you add energy, the particles have nowhere to go so it acts more like a solid.

When I was in middle school, we had a science project in which we were given a large ziploc bag and an egg. We had to drop the egg in the bag 1 story without it breaking, and we could only use one other kind of material. I did this exact thing, and I was one of the few to complete successfully.
i guess if you drop from a lower position, the protection effect itself will become weaker, is it?

if correct the non newtonian fluid turns solid when disturbed and when relaxed a fluid, well the egg is buoyant so it is on top, so when u drop the bag the turbulence causes the fluid to solid thus hold the egg in place and sponging it at the landing. and when it lands the solid is relax and at ease a fluid.

The formula is Cornstarch and water, in a 2:1 ratio. (( 2 cups of starch, then use 1 cup of water))

Its filled with something called a "Non-Newtonian Fluid". That means whenever heavy some pressure is exerted on this fluid, it temporarily solidifies and repels whatever hits it.

did you used the same egg for all the tests? :D
Terminchiator 3 years ago
Yes I did use the same egg for each drop.
I think it would have worked better if I had more fluid in the bag.
arthurschwieger 3 years ago
actually, i think the only reason the egg didn't survive ONLY on the 30 foot drop is because at that height, the egg was able to separate from the protection of the fluid inside the bag(by this i mean that objects fall at 33ft/second, and can distance from each other by any amount).
if you had done this in say, a water balloon, and only had the egg and the fluid inside(little to no air), it would have survived.
frank0127 3 years ago
acceleration is uniform regardless of mass
they fall the same speed, u are talking about the egg raising to the top of the liquid due to density reasons
it would have been much similar with no air

what is the formula for this?
jcps470 4 years ago
corn starch and water. I do not remember what ratio I used. That was very bad of me. I started with approximately 1/4 of the box (about 4 oz.) of cornstarch and about a half a cup of water. I hope this helps.
arthurschwieger 4 years ago
haha, when I did this project for school, one of the requirements was that it has to be made of materials readily available. Believe it or not I made a very successful egg dropper (tested at about 25 feet) out of about 5 sheets of paper and a couple strips of tape. Try to figure that one out :-D

medanielme 4 years ago
I did try it with water. The egg broke at 11 feet. So my drop at 22 feet was double the height.
Setting a good baseline of dropping an unprotected egg would be a good thing to establish. Then protect it with water in a bag. Ultimately, I could encase the egg in an acrylic block. That would survive quite a bit but it would be hard to use the egg after you were done.
arthurschwieger 4 years ago
i would think at the impact since the mixture becomes almost like a solid when uder pressure it would crack.
Griffdog28jr 4 years ago
Thus the whole reason for the experiment. If the pressure of the impact is distributed across the entire surface of the egg, we can use the freakishly strong natural structure of the egg to hold its own and stay in tact.
arthurschwieger 4 years ago
if the egg is completely submerged then the force is distributed around the entire shell (in theory) so becoing solid on impact is a good thing, because if it were liquid at impact the egg might hit bottom and smash the base.

Mabye if you used something like a dodecahedron as a container and suspended the egg in the non-newtonian fluid with rubber bands it would work better.
Nikayah 4 years ago
The construction of a dodecahedron would be more complex and would not provide much strength. But it would look cool! I could paint it up like a 12 sided die. I'm thinking a tube or simple box is the way to go for now.
I like the idea of using something to hold the egg within the non-Newtonian so it wouldn't float to the top. That would let the force be even distributed around the egg.
arthurschwieger 4 years ago
how does this work? doesnt non newtonian fluid act like a solid when it is hit hard?
camerond17 4 years ago
Basically, yes. At rest, the water wraps around each of the particles of corn starch and acts like a normal liquid. As you add energy, it starts to act more like a solid. If you stop applying energy, the water again works its way around the corn starch particles and acts like normal liquid. Fun stuff...
In nature you find this in the form of quick sand. In the store you find this in the form of Silly Putty.

very easy to solve with polystyrene. the box itself should be made from hard material like steel. first it would be much more stable (for many tries) and second it underlines your buffer-system as it doesnt absorb the forces from the hit. that way u should reach much higher levels.
blazey234 4 years ago
Good idea, thank you. In my world I am trying to keep it simple. I was thinking pop can or something cheap and easy. But I do need some sort of distance-keeper to keep the egg from floating to the top.
arthurschwieger 4 years ago
actually u need a sphere body with distance-keepers. as a sphere is much to complicated to build + to fill with the egg and the fluid a cube is practical as well. u can fill it and close it easier. u still need distance-keepers to the borders of the cube so the egg is stuck to the middle of the room.
blazey234 4 years ago

Darkclou222 4 years ago
How high?
arthurschwieger 4 years ago
I was thinking of a way to thicken the mixture to help keep the egg in place without it losing it's properties as a non-newtonian fluid. After a couple of minutes I thought to mix in styrofoam pellets. I think the styrofoam would be suspended in the mixture the same way that the cornstarch is suspended in the water. It would be lighter too for experiments with a weight limit.
boredinbr 4 years ago
darn 500 char. limit! A nested non-newtonian fluid on different orders of magnitude? I think I'll give it a shot next time I have some time on my hands and a couple extra bucks burning a hole in my pocket. Let me know if you try it first.

Will do. That is an interesting thought?

I've recently started theorizing as to what sort of practical (or entertainment) usages non-Newtonian fluids could have. I was wondering, for your experiment, assuming you used the classic cornstarch-water mix, what was your ratio of cornstarch to water?

arthurschwieger 4 years ago
i think i'm going to use your idea for my physics egg drop lab. We are dropping an egg from 18 ft. Should I use the plastic bag or make a container and put the non-newtonian fluid in it?
CrimsonCrescent 4 years ago
The zip-lock bag worked like a champ at 20+ feet so why do anything else. Easy entry and exit of the egg, as well as the non-Newtonian fluid.
One thing I wish I had done on the 30 foot drop was to hold the egg at the bottom of the bag so as it was falling, it would rise up and be somewhere in the middle of the mix at impact.
Let me know how your drop goes.
arthurschwieger 4 years ago
well, i tried it and it broke, obviously i did it wrong but we have a weight limit of 200g, the higher the weight, the lower our score and the lower our grade, hence why i think i should use something lighter
CrimsonCrescent 4 years ago
That is too bad! How about a smaller container. How much Non-Newtonian fluid do you get at 200g? That doesn't sound like much. How about a small block of polystyrene with a small chamber in the middle. Fill it with non-Newtonian fluid and your egg.
arthurschwieger 4 years ago
egg would have made it, jus it was in almost direct contact with the ground when they collided cause the bag was on its side. see....
T609 4 years ago
make a drop rocket, basically put the egg in a tube filled with the fluid and build a rocket or missle shape off of that center tube. so you know it will hit the ground the way you want it to. also if you want the egg in the middle of the tube (to stop it from floating to one side) try neodymium magnets im sure that would work.
MrOlafdotcom 4 years ago
How are the magnets going to help? The rocket design is great if you want to control the impact. I didn't not want to have that type of control. I wanted the impact to be a little chaotic. If you know from where your impact force is going to come, you can design for that. If you do not know, then you have to design for any impact.
My solution is very simple. The whole idea was to distribute the force of impact over the entire surface of the egg. This should make breaking it very difficult.
arthurschwieger 4 years ago
for the magnets, build like a little harness for the egg for a magnet on each side and 1 opposing magnet on each end of the tube. so basically the repelling magnets on each side keep the egg in the middle.. almost like invisible springs holding it in the middle
MrOlafdotcom 4 years ago
I see where you are going with that.
Even a better idea. Feed the chickens a very high iron diet. Then magnetize the eggs once they are laid. Then suspend the egg in a superconductor shell. Hmm? But then how to protect that from breaking?
If I would stop dropping eggs, they would stop breaking.
arthurschwieger 4 years ago
wat if u put it in a box with the fluid, full ,and drop it will it hav same result?
saltcar8 4 years ago
Nice idea! That should work OK. What I wanted to do was to keep the egg in the middle of my chunk of fluid. To keep it fully surrounded by the stuff. Even in a full box, the very top of the egg would not be well protected. But your idea would be better than my plastic bag!
arthurschwieger 4 years ago
i thought of my idea and just thought that regardless if the box was ful the egg would still sink to the bottem thus the egg will break unless the box was small enough to compact the liquid and keep it in the middle... pondering on again
saltcar8 4 years ago
With the mix is used, the egg floated! That was good so it wasn't at the bottom but it was bad in that it was not completely surrounded. With your ides, you could put a small piece of foam or something to help hold the egg down a little?
arthurschwieger 4 years ago
or you could put fluid ,foam ,egg more foam, the more fluid on would that work?
graffnameseed 4 years ago
The whole idea is to have the egg completely in the fluid. I would think a small piece of foam could be used to help hold it under? I think that would be worth a try.
arthurschwieger 4 years ago

graffnameseed 4 years ago
LOL 30 FOOT. I thought it was actually gonna survive that for a sec
TubeMan50 4 years ago
So did I. I think if it was totally in the fluid, it would have.
arthurschwieger 4 years ago
so a non-nutonian liquid will protect an egg to a sertian degree. you have to factor in weight, hight, speed, number of items being droped, and most important wind, if any. cool!
bigblue123 4 years ago
It sort of protects the egg. By distributing the force of impact around the entire surface of the egg at one time, the natural strength of the egg shell ends up withstanding quite a drop. If that same force was to be applied to a small point on the egg shell, it would fail easily.
It is kind of the same reason people don't get killed on beds of nails. The weight of the person is distributed over many nails vs. just one.

(thank you much). i made a casing with a small plastic ball. i used rubberbands to hold the egg in the centre area of the ball. when we tested it on beforehand, it registered forces of upto 500 newton before the egg before we had yolk. so we didnt just drop it at 12 metres, we launched it!

Thats cool... if you could stimulate the atoms present in a small space (like the inside of a car) you could use superposition to create a space in which there had ALWAYS been a non-newtonian liquid. Kind of like the car safety system in Demolition Man.
edm418 4 years ago
That would be a good safety device. That is kind of the whole idea around my experiment. I wanted to protect the egg. I think if it were completely surrounded by the stuff, it would have survived a much higher drop.
arthurschwieger 4 years ago
Undoubtedly! The practical application issues of this idea are how to surround the object in the first place... easily solvable with inanimate objects etc but the DM aspect could be tricky, unless you could get those theoretical quantum physics to work...
edm418 4 years ago
would you please conduct another experiment, one that would survive a higher drop? perhaps putting it in a short pringles can? what do you think?
sandinsx 4 years ago
That is a good idea. I used the bag because it was easy and quick. I think a better container would help. I also want to do something to keep the egg surrounded by the fluid. It was too buoyant in the stuff I made and about 25% or so was uncovered. If the egg were completely surrounded, I think it would survive a much higher drop.

What is "cornstarch" ???
xevian73 4 years ago
Cornstarch is used in cooking for thickening. You will find it used in gravy and other things. It is not the same as cornflower.
Cornstarch is a very fine power. It does not dissolve into water nor does it soak into the cornstarch.
The small particles of cornstarch are surrounded by water. That gives the mixture its fluid properties. But when you add energy, the particles have nowhere to go so it acts more like a solid.
arthurschwieger 4 years ago
