  • very cool

  • michaelilb2014 its not, broski.

  • It looks like...sand.

  • I'm sorry I'm a little confused why this is "strange behavior" and why people think its fake? Crazy shit happens really fast that we can only see with slow motion cameras. Maybe I missed something?

  • what the?

  • Comment removed

  • @darius2025tube Prove It, Oh That's Right, You Have No Proof.

  • :-O

  • is the sand mixed with anything because by my simple knowledge when i drop something on sand it just lands there, doesn't sink in.

  • @ilovegardettos well if you drop water on sand and record with a fast camera you should get about the same thing i think..

  • Who gives a shit what law it is?

    If water can freeze and turn into ice,then no shit that everything "solid" is just liquid shit with a gay ass low vibration.The reason why atoms and all that make up our world that seems solid to us.And the reason that atoms can act as waves too.

    The way that WE define a frequency in opposition to the REAL universal frequencies is about as hard as a nut to crack as it is to figure out the frequency inside a black hole.

  • I do have a question, though. At 0:01, there's a water droplet. In the latter half of 0:02, though, it suddenly disappears. Why?

  • @EnterARandomNameHere It is a reflection of the ball on the back side of the glass panel.

  • @EnterARandomNameHere The ball causing lens flare.

  • @EnterARandomNameHere well, I was convinced this was faked... then after reading some of these comments, browsing the uploader's profile and watching the thing again 5 times... I'm starting to think its just an experiment and that in fact, the video is not edited at all. The object that i suspected disapeared @ 0:01 does look like the objects reflection. Not sure that is ordinary sand though, looks like regolith or something.

  • It is true. The students at the University of Chicago have built similar, if not this very demonstration. Its a pity the video poster didn't take the time to include any information. Google search for "High speed video of freely falling granular stream." and you'll see another demonstration that they made.

    I remember reading about an award to some student for discovering it, but it didn't receive much attention in the "video game and porn watching" circle i belong too.

  • @darius2025tube It could be highly aerated sand, known as quicksand.

  • Comment removed

  • @EnterARandomNameHere Thats the reflection of the ball in the glass ;)

  • @EnterARandomNameHere thats not a water droplet, its the reflection of the ball on the wall of the glass box. :D

  • @EnterARandomNameHere it's not a water droplet, it's the relflection of the ball in the glass encasing the sand.

  • @EnterARandomNameHere That is the reflection of the ball on the wall of the testing chamber before it hits the sand.

  • @EnterARandomNameHere It's the reflection of the ball in the surface in the back.

  • hmmm...did anyone notice this video is shown backwards?

  • @michaelilb2014 So the ball floated up and out of the sand? XD

  • why is this so strange ?

  • sand mixed with air behaves like a fluid.

  • @awinn17 and @Spashdown

    Shut up. I don't know if you're disscussing because you want to look good, or because you're right, or something else. I do know this: you're bothering. I want to read serious comments, not your 'he said, she said' bullshit.

    For phuck sakes, this is science. Instead of just throwing random laws at eachother, provide effing evidence. Links, for gawd sakes. google, something!!!

    Anything to shut you up and let the others read important comments!

  • mind = blown

  • that last drop just Disafreakinpeared

  • Dry quicksand guys, look it up.

    Instead of water passing under sand, which creates "wet" quicksand, as you probably already know it, from movies and TV shows, and bogs n' stuff, air is passed under sand. This is the result.

  • If you think about each grain of sand being a H2O molecule this makes sense.

  • That was the coolest thing i've ever seen!

  • thuumbs up if totally MIND FUCKED

  • Sorry guys. Totally fake.

  • @Spashdown you're an idiot. this is either super fine sand or a fluidized bed. possibly both.

  • @awinn17 After working with flowing sands and other media in the environmental field and under varying conditions all over the country one should educate themselves first. Instead you should by quiet and have people suspect your ignorance rather than comment and have it confirmed.

  • @Spashdown you're making it worse for yourself. Go to a lab (like I have) and shoot a steel bearing into find sand at high speed. suprise, it does this. like jib1000 said below, sand is a fluid. Fluids perform differently based on their Reynold's numbers. An engineering lab (such as this might be) can quickly illustrate this for you.

    The boiling is caused by air that is pulled in behind the ball and later the sand that calls back in. That's called cavitation. Take a fluid dynamics class.

  • Comment removed

  • @awinn17 You are a silly goose. Get out of the lab and into the real world of performance. The reynolds number your refer to is very low and look into the stokes law. Silly little person.

  • @Spashdown how does it feel to look like an ass for all eternity on youtube

  • Super fine sand, it's a nice bullshit to play with.

  • bigger ball!

  • was that mercury ?

  • epic 

  • Sand is a fluid. Nice science vocab fail.

  • @jib1000 engineer or scientist? you sound like an engineer. whatever you are it's nice to see someone who can see things like this and not call fake just because they don't understand it.

  • That's not regular sand, it has been ventilated from below.

  • it would have to be shot into it for the sand to behave like that.

  • The ball was dropped at the speed of light, right?

  • 0:15 to 0:20 picture rosie odonnell taking a shit

  • O.O how heavy is that ball again?

  • I've seen something like this somewhere else. They use a high powered air pump to move the sand, trapping very small pockets of air. When the sand is struck by something, the air bubbles are forced out, along with some of the sand. Very cool video, thanks for posting.

  • That was just fucking cool.

  • The intellect of the average person is pathetic. Reading all of these ridiculous explanations as to what you are looking at are not far removed from calling it magic. "There's water mixed with the sand" its just really laughable.

  • SUPER SLOMO

  • thats sand?

  • the sand is mixed in with water, thats why it gets the air bubbles in it if it was dry sand, then the ball would not have gone all the way in to it

  • @Thedude441 I am pretty sure the sand is not mixed with water. It looks very dry to me infact. I believe its because when there are small particles of a solid object (eg sand, or salt) it can behave like a liquid in some ways. Its strange to see! Very interesting though!

  • like it was water but it was EPIC

  • what just happened?

  • that was fucking awesome

  • i dont wanna go to the beach now D:

  • that was weird and cool but yet if yuu think bout it we r looking at sand for god sakes waste of time lol .....

  • is tht quicksand?

  • whait a minute that happens when you do the same thing with water COOL :D

  • dude that was AWESOME!

  • epic slow mo

  • @rockfan233 That is actually someone sitting there with a camera that is set to take pictures very fast.

  • @rockfan233 That is actually someone sitting there with a camera that is set to take pictures very fast.

  • That was fluidised sand not just sand in a box ofcource that would NOT behave like that.

  • @dtiydr What do you mean by fluidised?

  • @Validole specially made extremely fine sand with air going tru it from the bottom at a very specific pressure so it act almost like a liquid, but that doesnt really behave like that on the vid so i dont know what else its in there.

  • thats pathetic that u all find this amusing

  • @KaraJayneee It proves your ignorance that you don't.

  • @meshumekha oh im sorry

    Oh wow!

    sand!

    it jumps back up and falls down!

    what a world we live in..truly amazing..

    hows that dick?

  • @KaraJayneee A long time ago, the Earth was nothing but a little ol' magma core with a solidified layer of rock and water all around it. Lots of water, right? Okay, so then cracks started forming all around that little core and the magma seeped out. Over time, the land was crumbled by water rushing upon it. And crumbled. And crumbled. Until it was so small, you couldn't even see one unit of it without a microscope. You get to watch it at 1/5 the speed. So stop bitching or GTFO.

  • @meshumekha Ohhhh

    okay,

    now I get it. your a nerd..

    well that explains everything.

    And If I am correct, which I am

    you started me, so If you want to continue, than by all means go right ahead.

    Cause im a very stubborn person, and I will "bitch" back

    so why dont you, go grab your dildo cause im sure thats all you can get, and shuv in up you ass :)

  • @KaraJayneee Okay.

    Now I get it. You're uneducated.

    And if I am correct, which I am,

    you submit to high school stereotypes and are proud of errors in your own character, which means you deserve no respect as a human being.

    Because I don't have a lot of time, and I will not "reply" to your post.

    So why don't you, not suck at punctuation and grammar usage, and spell the word shove correctly.

  • @meshumekha

    ohhh nice,

    really..that one made me smile no jokes either.

    NOW

    yes, I am very much in high school, and I honestly dont give a flying fuck

    towards stereotypes.

    And I have tons of respect thankyou

    and for your informaition I happen to be the best student in my science class..as long as were doing prac, theroy sucks.

    SOOO

    respect ma atoratar!

  • @KaraJayneee Talking as a physics student: In high school I felt the same about theory. Now, in university, I understand the beauty of theory: it lets you speculate about something you haven't seen before and still usually be half right. While I understand it's hard to see from your point of view: try to get the theory in your skull along with the prac experience. You'll appreciate the effort when you're older. Oh, and why this vid is important? It shows us something we can not yet fully explain

  • @KaraJayneee Face it piss pot, you can't win.

  • @reeytards I'm sorry

    didnt realise you were in this

    and for your informaition, is ended ages ago.

    so fuck up, get a life. and got over the fact that when something is dropped

    into sand, it shoots back up. not the greatest thing in the world love.......

  • sand mixed with some kind of liquid

    water or something esle

  • I'm pretty sure that was in a vacum tube :/

  • The Devil lives in that sand you know.

  • its called liquifaction

  • right all you lot think you know how its done but your wrong its simple what they do is they collet sand and then get a very light ball and then get harry potter to do a spell on the sand then drop the ball in the sand :)

  • ahaha i love you

  • I can believe that sand behaves that way naturally, but this looks like a it's a computer rendered physics simulation

  • this is incredibly high speed protography

  • @Creaform003 this is slow motion.

  • @ViralFlow yes high speed photography is when you are able to capture very fast motion you are unable to see normally but thenslow it down alot

  • what that is is ultra fine sand and it doesent react the same way as normal sand becurse it containes air between each corn ... i think so :)

  • all the sand i have ever encountered acts nothing like that :/ what is that super sand or something?

  • i think its in an air tight container

  • i don't know about you guys, but that was pretty fuckin' epic...

  • @zx6rtt More than epic!!!

  • @zx6rtt yes. pretty fuckin' epic

  • Looks a bit like quicksand..

  • thats only water and sand,

    it was shot at a high velocity

    quick sand is more like

    "wait a hour to sink a foot"

    sand.

  • is this sand wet?

  • An engineer friend of mine told me about this - the sand isn't wet but heated to 500C, which gives it weird fluid properties.

  • oh i see. thank you.

  • you mean an ejaculation, or?

  • Maaaaan!

    This posting is hilarious!

    Cuz like I alwayz been wondering how I like when even wearing speedos when lying on the beach I still get sand up ma crack!

  • that is awesome

  • Cool

  • water has more of a crown

  • sand was aired

  • IMHO the ball is not being dropped in, but is being fired in at high velocity. The quantity of 'ejecta' from the impact would be consistent with the energy involved. Some moon craters have rebound peaks in the center. This video is an excellent demonstration as to why! Oh yeah, video is obviously slow motion.

  • obiviously u have a aair compressor under there or something

  • no the ball was shot at a high velocity it is a rebound peak if you read the comment above yours he explains in more detail

  • Amatures...

  • It's a sand bath. The "sand" is as fine as talcum powder and they have air fed in underneath. Normally the sand heated to ~800degC and it's used to clean metalalic machine parts (such a very fine die holes in nylon fibre extruters). Just drop them in and leave it to soak for a few hours.

  • how is it fail?

  • previous comments.

  • Oh.

    lol

  • how is it FAIL?

  • All kinds of sand that I know do not allow things to sink like that. There is just one exception to that - quicksand produced with vibration or air pressure from below. The other possibility is that the potter from earlier is right and clay behaves like this but then it is not sand. Even if the composition of both are the same, the physics are not.

  • its hella fine sand used for sand blasting. its cleaned and shaped

  • I could reproduce this with glutenous rice powder used for a Japanese dish. It works if it is more like dust or powder then sand.

  • You're all wrong.

  • just to put an end to people saying the sand is wet, its not! if it was then cohesian tension would form droplets when the sand splashes up.

    It is just a ball being dropped into sand, or mabey the air pressure thing some people have talked about, but to me it just looks pretty much the same as if you drop anything into sand.

  • Wow that's pretty cool, and thanks for the explanation people!

  • lol this is great

    but if u dropped any thing from a certain height into sand it would do the same thing.

    Even with asteroids/meteors If u were standing MILES AND MILES AND MILES AND MILES away from an meteor colliding with earth WITHOUT GETTING BLASTED OFF U FEET BY WIND OR SOUNDWAVES. u would feel the earth FLIPPING u over>

    IF U COULD WATCH A METEOR COLLIDE WITH EARTH AND NOT GET HURT. U WOULD SEE THE BIG SPOUT OF LAND SHOOT OUT LIKE A VOLCANO....therefore it isnt that weird

  • Displacement

  • thats also what happens when a metorite hits earth

  • how kool is tht

  • OK, sand, now give me the ball back...!!!

  • I wouldn't call that strange behavior, since it's exactly what I expect. I've played with sand plenty to know its water-like behavior. I'm sure any solid with enough freedom for movement, and enough force impacting it, could move like water for a moment. Especially in watching model tests of meteor impacts.

  • is that sand mixed with water?

  • explain very early in the video there are 2 balls one large and the other small and then suddenly it disappears? Why is it in such a perfect square box? clearly dude i dont see why does this does not look like graphics to you... 3ds Max and RealFlow a simple application of water simulation to a bunch of particles that appear as sand. If u dont believe me do some 3d modeling or watch the videos of ppl doing 3d simulations because this is clearly an excellent one. c'mon ppl

  • im pretty sure the the 'little ball' disappears because it is only a reflection in the glass of the 'larger ball' its in a perfect square box because he wants it to be in a perfect square box... why is that bad?

  • it actually looks like droplets man.. i really feel strongly that its graphics.. disappearing droplets.. weird... and the way the sand drops...

  • @mongoosecage did you ever consider that most shapes in labs are like perfect square boxes and perfect circles?? oO

    you obviously never worked in a lab before...

  • @mongoosecage did you ever consider that most shapes in labs are like perfect square boxes and perfect circles?? oO

    you obviously never worked in a lab before...

  • @BUFU1610 no.. the come in beakers they dont really look like circles, well i had a different comment also not refering to the shape of the container, my point is that i am still disputing the fact that it is graphics or real due to the propertiies of sand and the disappearing second metal droplet.

  • @mongoosecage what second metal droplet?

  • @elevadon 0:01 check it out, above .................ohhhhhhhh shittt.. yeah its real my bad

  • @mongoosecage ohhhhhhhh ok sorry my bad, i thought there was a second droplet at 0:01 :S stupid stupid,  just realized its the reflection.

  • @mongoosecage must be a special sand, doesnt look like an ordinary one.

  • @mongoosecage It's probably taking place in a vacuum.

  • momentum reaction force

  • those are some mad hax

    and wow some of the people trying to call this fake just flat out fail at it. Sad to say that their skill is not enough

  • people, sand is just like water, except it isnt wet ;)

    cuz every tiny particle of sand is like atoms in water...

  • a "Particle" is thousands of times bigger than an atom..........

    Water is smooth and the basis for life, Sand is coarse,dry, and its just earth

  • HAHAHA PHYSICS FAIL

  • ajaja parecen dos videos superpuestos...uno de una pelota y otro de un impacto de bala...muy loco

  • cool

    use colored sand or something

  • Its sandtastic

  • lol

  • it looks like water

  • Guys, sand is like a perfect model for liquid stages of matter. Each grand representing a atom which can move a bit but isn't independent of the whole. No wonder it behaves sort of like a liquid

  • maybe the bottom is like a trampoline or something

  • us this sand dry or wet or what?

  • looks like dry sand.

  • Its weird that little "tower" rises after the first one and then in the end the last ball-like sand "explosion" is weird too , it rises just after the moment when everything should have calmed down.Like it god some magical extra energy from somewhere lol :D

  • Yeah, the magic of wave reflection.

  • cool mon

  • not real. but still cool

  • that was cool

  • 0:02 where did that tiny drop go?

  • Its the reflection of the ball in the glass.

  • ok i see now...

  • wtf? r u kiddin?

  • wtf?

  • guys being a potter i mix my own clay and the fireclay and yellow clay i mix together in a 15 gallon bucket literally feels just like water...i can put it it between my hands and squirt it lol...it feels like it bends the laws of nature...i have dropped d sized batteries in the bucket and they go straight to the bottom idk what happens i think it is the lack of friction but it is some crazy stuff...it really acts jsut like water idk what he is using but i dont think it is CGI!!
