Do Try This at Home - Season 2, Episode 3 - Summer Slow Fall

[bubbsyd1999]

i wonder if it would float if the tube horizontally

[aemarengo]

Epic T-shirt bro!!!!

[SuperSuperWaves]

I like your vids thanks

[oregonboy323]

it didnt even touch anything

[FeRoReflex]

Mr. G i believe you are nice to this little kids and dont cuss them out you are the nicest person on youtube!!!

[ScoutTarget]

Householdhacker copied your experiment :C.

[gamedevil12]

@ScoutTarget lol was thing the same thing :P

[figisligit]

i think i know how it works!  its sorta like a generater. if you move a magned around a copper wire, it generates electricity. andwhen copper has a current, it becomes an electromagnet. so it is not magnetic, unless the magnet if moving through.

[rubiks56]

Mr G you're vids are a new favorite to what I watch. You're just like kip kay. You show easy projects that you can do at home. I love your vids . have u heard of Kipkay?

Pleeze reply. Rubiks 56

[computerpro101]

I wonder what would happen if you put the small tube into the big tube and then let the magnet float down?

[Fallout3Fanboy97]

Drduck, the magnet and metal ball got stuck not the pipes -_-

[DrDuck1708]

If they don't attract to the copper then how come you had to use so much energy to pull it away from the pipes at the start ? :S

[xLastChaoS98]

@DrDuck1708 the ball magnet stuck at his disc magnet

[xLastChaoS98]

@DrDuck1708 the ball magnet stuck at his disc magnet

[DrDuck1708]

@xLastChaoS98 Oh...I see, My mistake :)

[JonathanSarabiaTV]

Cool

[gogokoko95]

Mr .G your mind "blows" alot

[thatGUYbehindthemask]

Fucking magnets! HOW DO THEY WORK!?

[salahhe]

I stumble upon this video, I tell myself "whee! i get to subscribe to another cool channel" and then you don't tell us why that happens. Disappointing....

[XxactiveshermanxX]

its do do with the magnet ball is repelling the copper pipe

[TheDavexiv]

i gotta say i love wathing your videos u are the man

[coastermania17]

that seems very similar to how the liquid metal outer core of the earth flowing around the solid inner core creates the earth's magnetic field

[TacoDude314]

Love it. I saw that at my dads University but I've never seen it at that angle.

PS: What kind of tri-pod do you have, I think I have the same one.

[aajjeee]

do it work with neocube

[vladokid24]

zero gravity in gravity

[adamisSLAK]

ahhh very good sir!

as a physicist i know that since the magnet is cutting flux lines and EMF is produced....this is a force for you guys :)

now an EMF always acts in the opposite direction to motion, this is called Lenz's law :)

now as the magnet is falling and the copper is cutting through flux lines, the force produced is acting in the opposite direction to the falling magnet :D

therefore...the magnet slows down!

pretty cool too.....

[TheLenart001]

dear MR.G i think your videos are great continue doin your videos ^^

[redbeard716]

lol @ "Pipes of Cu" I was also wondering a couple things: what would happen if you added more magnets does the effect increase? and if you put the smaller tube in the big tube does it negate the current?

[vuvffufg]

i saw this on head rush has something to do with the copper properties

[thisguy235]

Did you divide by zero?!

[OliviaRoberts12]

so u cant use just plain regular mag.??

[chriswww]

You should make a Magnetic acceleration gun.

[paroutdiok]

i like the bloopers!

[dakasd]

try to cut the pipe from one to another end , the magnet will fall like a rock

[moggis12]

Haha " This lighting blows " :P

[aducu3]

Hi i am mr pee hahaha and i am 10 what an insult

[SuperShelbygt525]

THATS AMAZING!!

[thewitycomenter]

iz 13 and a cook

[thewitycomenter]

iz 13

[therealcruz]

this is awsome



[TheMeikamanne]

What the f***????? how's that possible?

[kernulklink001]

F***ing magnets! How do they work!?

[knifenut67]

makes you wonder if you were to cover yourself in those magnets and got inside a giant copper tube........moon simulator?

[SonyFoLife]

after reading lenz's law on wikipedia, i wondered: of the pipe was thick enough, could the magnet transfer all of it's momentum to the pipe and essentially just float there?

[Stadtpark90]

More questions:

The moving magnet decelerates and after a short while settles around a certain speed in the tube. Is this time (or the length of the tube needed to achieve full slowdown) direct proportional to the acceleration?

In one of my last posts I implied, that on the moon the time it took for the magnet to pass through the pipe would be the same (- because the speed of the magnet in the pipe would be the same.)

But now I think, if the pipe is too short there'll be a difference.

[Stadtpark90]

If you did this on the moon it wouldn't take longer to fall out!?!

Gravity is weaker there, so the magnet would move slower, thus inducing less eddy current resulting in a weaker magnetic field, which would slow down the fall less. But is it linear proportional?

For the speed to be slow you need high energy density of the magnet, and close proximity to the tube (magnetic forces diminish with distance ^3), and a low resistance material. Main component being distance right?

[Stadtpark90]

Energy-density: a N=52 magnet would slow down about 20% more than a N=42?

Resistivity: a silver tube would slow down about 5% more than a copper tube?

Electrical Resistance: doubling cross section (thickness of the tube-material) would half the resistance, thus doubling the eddy current and the resulting magnetic force (100%)?

(Air-) Distance between magnet and tube: half the distance results in 8 times the force (800%) - but more air looks cooler!

Ever tried a coil instead of a tube?

[Stadtpark90]

@Stadtpark90

LOL - I should have looked in Wikipedia instead of trying to figure it out myself from 10 other sources...

Copy & Paste from Wikipedia Eddy Current entry):

- stronger magnetic fields - increases flux density B

- faster changing fields (due to faster relative speeds or otherwise) - increases the frequency f

- thicker materials - increases the thickness d

- lower resistivity materials (aluminium, copper, silver etc.)

[Stadtpark90]

The first time you lift up the tube while the magnet is in it.

But it doesn't seem to fall out significantly earlier than with the unmoved tube!

My explanation:

The magnet itself is falling with the same speed (the gravity doesn't change), but relative speed between the magnet and the tube in the moved/lifted tube is higher, thus the induced Eddy Current and the corresponding magnetic field is stronger, so it's getting slowed down more. Is that right?

[Stadtpark90]

Just a few hypothetical questions:

The Eddy current heats the pipe, because it has electric resistance? Would it be measurable?

If the tube was a superconductor, the induced Eddy-current would never stop?

If you repeated the experiment a few times then, would the Eddy-Currents of each cycle add up, so at the n-th cycle the magnet wouldn't come out at all, but be stuck floating?

If so, what number would n be? 2? 10?

Is there a way to calculate the force of the Eddy Current?

[hammad9980]

Why does it float?

[wurft]

14 people don't have copper tubes.

[MrJebus3000]

Hahaha.. Love the shirt..

((I always wanted to be a procrastinator, but never got around to it))

[DarthOptimus207]

nice shirt

[Supersupernatify]

i love the mistakes at the end they are hilarous! Plz make more of these!! Im 11 by the way =)

[jjpjful]

y do u look like that wrestler when i pause at 0:48? Answer plz.

[1224force]

the air has to go around the magnets so it makes them go down slower

[HaloMasterSpawn]

you should become a science teacher!

[nofishhere4]

are you a wizard?

[ScarOnMyAss]

he bought the bb and magnet from chuck norris

[00wekfet00]

O_O

[Djaixifity]

IF i saw it i was thinking if u build a box of copper where u can go in and u make a magnet armor for ur self do u can fly :D

[papertoy1000]

it is greg

[papertoy1000]

what is your reel name im10

[Mindpaint]

@papertoy1000 My real name is listed on my channel. I hope you are learning a lot from watching my videos. Ten is a good learning age!

-- Mr. G

[beastlyairsoft67]

@Mindpaint i am learning alot i love your videos



[coolskater26]

@papertoy1000 ha funny im ten too!

when i grow up i want to be an inventor:)

[QoSRULES]

@papertoy1000

im 9

[luigiandyoshikickass]

@papertoy1000 im 10 too 

[iampinkchiken9]

i wish you where my science teacher

[Inyasha1139]

Neodymium magnets are as strong as hell :P

[mihai1705]

i wached only to 3:17 and i realized its air pressure! isn't it?

[Mindpaint]

@mihai1705 It has nothing to do with air pressure.  I assure you!

-- Mr. G

[27Koda]

@Mindpaint thanks mr.g i made my classmates minds boggle fromthis and other videos :)

[boomboy1020]

O_O wow soo cool where do you come up with all of this stuff?

[mr1Spidyman]

that is so amazing

[Crfreardon]

Mr. g i have a question the smaller the magnet the longer it lakes to make it to the bottom of the copper pipes?

[tomsindahouse]

I'm not sure why i still watch this, i just love the way it travels down the pipes. Awesome show Mr G. =]

[rambo0356]

Does it also work with other pipes than copper? ps. I love your vids they're so awesome, I think I saw all of your vids. Good job. Also love the vids from Do try this at home 2010

[Mindpaint]

@rambo0356 Aluminum also works very well.

Thanks,

-- Mr. G

[MrJaNowly]

@Mindpaint Ok thanks

[legocreationmaster]

how does it work???????

[azza061294]

@Mindpaint could you do this but when its neer the bottom tip it the other way so it falls back :) if you can could you make a video response :)

[WoWCraftStudios]

Magna Foarcez

[swallowthedark]

lol i love your shirt

[yehimbored]

lol are those gun shots in the background?

[MrWhoisready]

the power of the trees!

[toonarufo90]

4 secons

[rsredfunk]

The copper pipe is not magnetic, and that magnet he got which he put down the pipe resist to touch the inside of the pipes because they are "not-magnetic" and the magnet is magnetic.

[MasterPokemon2000]

wow

[tomek123kotek]

nagnetic drag caused by induction currents ftw!!!

[chris7toronto]

I wish you explained it but its awesome

[Jarrheadd00]

I gotta say Mr. G, it would be nice to have the experiment explained. Mind-blowing experiment though! Great job!

[TheSlavedBoreChris]

Mr G, i used to hate science but now that you should be some cool science i like it thanks!

[nicko2444]

awsome!!!

[LiiMuRi]

This is my favorite of your videos (this far), simply because of the simplicity, cool effect and the physics involved.

[HectorL360]

it'd be awsome if there was a ride where theres a huge pipe and you put on a magnetic suit then you just go down the pipe

[alexgherghisan]

no i'm sure that you don't see me

[lolli805]

Theres hidden magnetic metal inside the pipe(gotta google Lenz`s law)

[MrJaybobz]

Hey Mr G Try putting the smaller neodymium ball down the copper tube thats got the bigger hole and see if it still floats,

lovin the videos :)

[Kuczerski]

Very cool! If you can send me an explain why it goes so slow in the pipe so would it be super =)

[Zevrinia666]

If you could post an explanation for this, that would be awesome. That was very interesting though. Thanks! =D

[113qazz]

dude that blow my mind its like something from sci fi

[ABST666]

hehehehee MR G youre very nice.......

[insinerator09]

procrastinators unite tomorrow

[heartskittlez720]

awesome!! :D

[PoisonusPotatoes]

in and out

twss

[Amazing1h]

That would be a cool elevator system if they built it large scale

[ScarFace9797]

it would be if you could pull it back up easy enough

[rafaello550]

wow!!! cool

[IDidItForTheLulz200]

I work at a metal recycling company, I'm gonna show this to my coworkers! They'll shit bricks!

[Patfire73]

how does this work?? :S 5/5

[orenco]

OMFG THIS IS SO COOL!

[ultiomos]

PHOTOSHOPPED!!! :P

[LilT1232]

that is a cool experiment. i love science. good job keep it up.

[nascar777man]

wtf

[BionicleKid97]

You can also do this if you get a positive magnet tube and a positive magnet. They rebel causing it to float away from the edge. Or fly out.

[kismet1337]

Nope... as far as I know, single poled magnet do not exist.

I heard about shielding one pole with a non radiationable material, but I can hardly believe that this works.

[BionicleKid97]

It is amazing. But Idk if magnets shaped like poles exist... I think they do.. >_>

STILL FRAKIN' AWESOME!

[Narukai12]

static?

[ANAstarproductions]

This is absolutely amazing! I'd love to try these! This really is mindblowing : D

[guitarhero3rox97]

the friction of the magnet and copper make electricity and then it slows down

[kelvin1303]

"That blows my mind everytime I see it" 3:43

LOL u're cool!

[harshsilver]

crap.........

[ruicarl]

yay 500º rate

[TheCheese30]

nice vid :)

[wakerzeco]

100% Cool

[bestSVMS]

If you can find some alumin foil rolls with a small core( smaler is better), it also works. Looks cooler with a square magnent. On tv there was this super strong electromagnent, they dropped a aluminum ingot in, and took 2+min to come out

[Squeedly135]

i wonder what happens if u push the ball bearing or magnet or w/e he called it from the bottom of the tube up to the top... i wonder if it would make it all the way up wto the top of the tube :P

[anasyasalam]

cool

[UncleSluggy]

Thats AMAZING!!!

[uberspork123]

Has anyone actually read the description of the video? The magnet induces a current (Eddy Current) in the copper pipe, which creates an electromagnetic field. That field acts against the falling magnet, slowing it down. Think of the flashlights that you shake to charge. They have a megnet and a copper coil to generate electricity. It has nothing to do with air pressure (the pipe is open at both ends!) or compressed magnetic fields.

[mousedaga1]

i think its because of "air pressure" , when the ball rolls down, it's surrounding is compressed (tube), thus, forcing the air to block the ball, and making it roll slowly :)

[bestSVMS]

try it with a steel ball bearing and it wont work.

[2000jjh]

awsome

[jokestah]

i think its because the copper pipe is a repelent so it slows it down i think

[lmnop821]

THAT WAs totaly AWSOME!!!!!!!!!!!!

[fjlj]

when a magnetic field is compacted into an area that it is unable to escape it effects the magnet itself.. so it is "floating" on a co=loud of pushing and pulling magnetic fields running into eachother over and over...

[kelekilla]

reallly cool!!!!!!!

[jojojojo560]

that was AWESOME!!!!!!  i really like his experiments!

[TheJarosM]

u are awesome

[SightlyAbyss]

i like watching the bloopers

[SightlyAbyss]

hey i have that same tripod for my camera its a good tripod its easy to set up and easy to put aaway

[thejasonmaster21]

now that was awesome

[theflyingace1]

get better experiments

[norisak]

Thats is AMASING!

[sfulk609]

this disapointed me when you didnt explain why it happened

[jde8568]

what size magnets did u use???

[JktuUekmw]

OK,THAT was awesome ))

[prasiatenko]

Awesome!!

[DrummerX95]

haha "procrastinators unite! Tomorrow nice"haha

nice vid too!

[Miamidfinsfan1326]

amazing!!!!

[chatchachan]

u rock i love u and i love science make more video and u rocks

[ChloeLee1969]

u are funny!!

[kavo456]

PIPES OF COPPER!!!!!!

[jj31596]

they should put copper in the roads and magents on the bottam of cars so they hover ^^

[Dannytheunderdog]

but how would you move? and turning would be nearly impossible

[110194ghost]

that was awesome 5/5

[icekenner]

thats soooo cool  5*

i love the experiments you do^^ plz do more of "Do try this at home"

[dudemanman252]

mr.G = Gman?!?!

[DrummerX95]

i agree

[littlemissAlexis]

I wish you were my dad..you are soo cool!.

[heyhay98]

branch killer!

[DustProductions13]

Hey You should try spinning them before lettin them go and see what it looks like

well anywho your freakin awesome

[poptarttoshi]

could you flip the tube over and keep it gin forever

[zaxtarda]



[boomman2u]

lɛntsɨz? lol

[DJNIGHTREX]

dude that was awesome !! by the way i have the same camera stand !!! :D :p

[yurt101]

i don't get how exactly it works... coppers non magnetic yet it goes slow as if it affects the magnetic pull yet its non magnetic...

[gigityman2]

the reason it goes down slowly is the magnetic feild around the magnet and antimagnetism

[RhiannonMusicMaster]

i luv those magnets, i heard somewhere that if you put one on one side of your arm and the other one on the other side it would stick togheter, did anyone try this?? i don't know if its true

[asif474]

i do that with any two magnets i have. only small magnet can only stick at fingers

[troggdor4]

i love that shirt

[drakeconstant]

Holy Fricken thats cool

[drakeconstant]

Your not mr.g ......Your GOD!!

[Rozbeanz]

I've got a couple pipes of copper, hello I've got a leaf in my face hahahaha

[RQCKER88]

hey how do u get the magnets that big, i could not find them that big, the ones i saw where like half of a penny, please answer.

[GeniusoftheMind]

Mr. G is God.

[MoPar7055]

Could you explain how this works?

[docsharp00]

Foucault currant and Lenz law. when the magnet move in the tube, a curant iappears (Foucault curant) and créat a magnetic field. the magnetic field top direction oriented just "attract" the magnet to the top. so the fall is slowed.

[Brookbadger]

thanks
