Anti-Gravity Water - Sick Science!

[nickmv00]

How come I want the background music.

[Supercooljordan12]

Did this without any of those materials just a cloth/cup/water and that's it

[AnimeLover2k]

well obviously the water isnt going to go into the bowl beacuse there''s a wet cloth keeping it in the glass ._______.

[biddycy]

*yawns

[simman4427]

vacum is created!!!

[Rampagedon]

compression of air maybe?

[yoshifails345]

WOH you didnt show teh glass upside down without the cloth

[iotubi26]

@yoshifails345 cause thats not supose to ever happen? the "trick" was that the water wouldnt fall through the scarf

[Mawukoattivor]

cool



[pivotmaker1123]

i poured water all over myself

[ChrisMax360]

i don't understand :/

[stardollfanful]

Its bacicly makes an air tight seal



[DualcastBahamut]

Surface tension. That is it. Yep. Surface tension.

[gabrielsebastian74]

the water poured after created a seal with the glass, not allowing air to comee through to occupy the volume of water inside the glass. Or, again, the force.

[Kleo3392]

I think chanjongjung is right it is negative upward force when you're pushing down with your hands you're kind of creating a vacum but this is just a conclusion that I came up with I can't be sure until I run some tests.

[rakeshkumar47]

i invented this when i was 4 years old, i used a tough smooth paper.

[minecraftgod1]

Well when you flip the cup it seels the air bubbles creating a suction

[ELOKODELCASKO]

wow cool



[XPolyVerseX]

same reason a straw will not release its contents if one side is closed

[442hoeky]

@XPolyVerseX Not true. The straw trick is related to surface tension and hydraulic friction in the straw itself. Try it with a 3" wide straw and it won't work (the surface tension at the open end is not enough to hold up the water). This trick has to do with a vacuum in the glass above the water and the air pressure pushing against the cloth napkin.

[sifer82]

The Cloth is filled with water not letting air enter, as he turns it upside down. Thus creating a vacuum seal. Allowing it not to fall.. Am i right, or am i Right?

[MyNameIsJohnFalcone]

Black magic!

[moody1722]

@MyNameIsJohnFalcone white magic XD



[EpicLol21]

science xD thats what the blue letters spell at the end

[usaf2020]

The thyme is off-key at the end.

[Simpleplan2300]

Just air goes out

[TigerClaws12894]

8th grade physics and they still got it wrong....LOL

[59Ballons]

notice how at the end of the video the colored letters spell out the word "science"

[panzerelite195]

@59Ballons the test tube is suppose to be the "i" =.=

[TJDTaylor]

@59Ballons I could never figure that out, wowim dumb.

[yondaime500]

@59Ballons it's a subliminal message brought to you by GLaDOS.

[wrexify]

It's because the handkerchief has some anti-gravity substances in it when water goes through the gaps making the water not able to go through the handkerchief.

[VlD30z]

@wrexify There is no such thing as an "anti-gravity substance."

[MikeColosi]

@VlD30z prove it.

[jennifer401000]

@MikeColosi have u ever saw a floating object in regular air?

[perkypears]

@jennifer401000 yah a plane :D

[antonio0076]

@VlD30z ....dark energy is anti gravity.

But this vid has nothing to do with anti grav...lol. Its a pressure differential

[TehGoodGamer]

The water stays in the glass due to a vacuum, he vacuum stops the water from escaping otherwise there would be nothing to occupy the space within the glass.

[MrSmileyFella2]

Did anyone mention that you have the cutest background music ever?

[ScrumptiousWhipple99]

The video is Neat!

[FrAgStEaLeR4490]

take a little piece of paper such as A7 or so and do this. much easier than with that big cloth thing :D

[snantafrd]

its related to atmospheric pressure

[hahann0099]

I'm guessing it has something to do with pouring water inside the handkerchief? and water filling the gaps in the handkerchief?

[JoystuckTV]

It's not a surface tension..

It's simply an atmospheric pressure is bigger than the hydrostatic in the glass.

[justajiffy123]

@JoystuckTV is a KILL JOY.

[DoseOfTech]

Doesn't it create a vacuum?

[chanjongjung]

not surface tension, negative upward force... if that was surface tension, we'd be pooing water -.-

[djlegacy96]

@chanjongjung i have done before

[Rulerofwax24]

@chanjongjung I'm not exactly sure what you meant by 'negative upward force' but what is going on is air pressure is pushing the handkerchief up. You might know that air pressure is 15 lbs per square inch. Say that is about 2 or 3 sq inches, there would have to be 30 lbs of water pushing on it.

[PeonyGranger98]

It is because the air pressure in the wine glass in larger than the open air, so that the water can anti-gravity :D

[Boeing737Channel]

Also works with a straw...

[RaymondoLordo]

Isn't this capillary action?

[EnragedSephiroth]

Back pressure caused by the surface tesion of the water in the cloth.

[tylerk648]

Ok. This guys is hot! Lol.

[MrDodgeball18]

Surface Tension? no..... the air pressure on the outside is greater than it is on the inside of the glass... derp

[AdamTheGuitarHero]

@MrDodgeball18 Both principles apply here!

[phMoca93]

We've learned this in 4th grade in primary school. xD

[pakiking1993]

If u use a peice of paper u can actually remove the paper and hold the glass upside down without it spilling out

[pleikul]

H BONDS!

[Atomkiller007]

lower air pressure inside the glass causes pressure from the outer side against the nap.

[radivoactive]

Vacuum

[lolydodo123]

I beleave it was.. Pressure. And the fact that the air was inside, and could not escape. SO the water couldn't move either

[BrandonKAli]

i think is would be that the wet cloth would allow for the air pressure to balance of and hence no movement seeing that pressure moves from higher to low but since there exist no difference of air pressure there wouldnt be any movement :-)

[MrSteve1254]

Vacuum



[xxBASEBALLxSTARxx]

you can do that with an envelope put the envelope on any cup of water and while holding the envelope, flip the cup over and let go of the envelope

[johnboy3331]

because between the scarf molecules there is water.... so water cant pass through it self.... but if u push it will fall down

[melodysoe]

i thought water could float!

[AlloraLang]

I saw this on a Beakman's World episode. The air surrounding the glass pushes up on the handkerchief more than the water pushes down on it. Fact is, you would need a glass almost 30 feet tall before the water would weigh enough to push it off the glass.

[Peopleunit]

Molecular cohesion of the water molecules prevents it from draining through the cloth, in turn preventing any more air from entering the glass, so the water stays put.

An equally cool feat can be achieved with flammable gas and a screen. That's how gas lanterns work.

[comedyman9]

Surface tension. Yet again!

[StarsHugMe]

PUH-LEASEEE .

I did this when I was younger anyday .

[iReplaay]

Cool :P!

[folledyousucker]

that anit science



[russiangooglespy]

a vacuum is created

[cm79ca]

it's a vacuum... keeping the water in place while you tip the glass.... if only we could find a practical use for this... :D

[waffletaco13579]

you can do this same thing with a normal cup and a poster card

[RedStrawberriez]

Amazing video, there should be less dislikes!

[NINJApandaLOVE]

The air in the glass forms a vacuum as it is flipped upside down.

[joesatmoes]

ive done something similar b4

[Sihgilanu]

SURFACE TENSION! :D

[cfaztlan08]

the hanky creates a suction cup of the glass and stops the water from falling

[thabluetshirt]

AIR PRESSURE!!!

[chompmyclit]

Air pressure is awesome.

[D3mang3l]

It's the same thing that makes a Barometer work, plus there is surface tension and capillary action. The napkin creates an airtight seal because the water is drawn into it and surface tension plays a role in keeping it sealed as well. Then because air can compress/expand and water cannot, the force of the air pressure outside the glass is stronger than the mass of the water, and the air inside the glass requires a certain amount of added force to be expanded. That's pretty close.

[Kyoshiro5411]

You put a scarf over a cup. ..I can do that. not to be a troll or anything.

[toukta9]

i do that all the time except i only use a cup and water and i don't need too have a certain amont of water

[sihayra]

I think this happens because the water goes through the scarf, and as you pull the scarf tight, the water goes through the scarf, but the air doesn't. That way you create a vacuüm between the water and the scarf. The vacuüm keeps the water and the scarf in place, and that's it!

[14reynoldsm]

The wet scarf creates suctioiin cup effect inside the glass.

[TheWarCandy]

I hate it when I clicked the "Check out steve's new show" annotation and it doesn't open to a new tab

[Raymax642]

Great demo for kids showing the surface tension properties of H2O

[WinbookXL3]

i done that with a water bottle

[reincarnage256]

i like the do de do song

[jimmyjamjar10101]

I used to do this with a little bucket and a face washer in the bath tub when I was little lol

[wildchildmatt]

when i saw the thumbnail, i thought that the water from the bowl was going into the glass

[EpicSoulChick]

it also works with a playing card xD and a normal plastic cup (I did this expirament in grade 4)

[ShinyUmbreon13]

I LOVE YOUR CHANNEL!!!

[Phenomiphy]

Scarf is like a vacuum

[princessdedeism]

i think the hankerchief held the water in one place



[lordHz]

You guys are dumb !!!

[NINJAxxPH0X]

This guy has a different plain tee every video... And I've been watching a lot of Steve's videos... xD More to go! haha

[rojerangelo]

i dont get it :l

[pepperannehanson]

I've done stuff like this before. I do believe that the wet scarf would help create a vacuum because with it being wet air cant come in and replace the water so it stays put.

[donnajos]

Woo! Surface tension!

[colinprprpr]

@donnajos Not surface tension actually. The wet scarf allows no air to pass through and the atmospheric pressure on the outside of the glass (and scarf, and EVERYWHERE for that matter) pushes on the scarf more than the water pushes down on it. So the scarf keeps the water inside. Only works when it's wet, or else air goes through. Try it with something like a coaster also.

[jemimaurcia]

I think 226 people thought that the water would fly.

[RabidDog51]

@jemimaurcia more like 443

[Joshuology]

@jemimaurcia 362

[Ademzify]

Thats not anti gravity that forced anti gravity lol

[gigsters42]

I used to do that when I was like 4 with a washcloth and a cup in the bathtub.

[cirusMEDIA]

ummmm.... i don't like! :/

But i guess some kid out there will have fun with it anywayz!

[jason950216]

extensive hydrogen bonding between H2O molecules create a large amount of surface tension

[moonomo]

its not Anti-Gravity maby thats why so many dislike.

[xxxKenseIxxx]

wow, ive never heard of vacuum before

[Mac1634]

Oh surface tension, you so crazy.

[greggr88]

surface tension

[skaterdudeAWS]

How many people paused at 0:57 to see if the blue letters spelled anything and noticed it spelled science?

[SuperMineyOBros]

It creates a vacuum!

[malcior180]

I love this trick, its almost the same as using an index card

[marcos54695]

You can use a sheet of paper too and looks better

[CupcakeMadness637]

its a vacume

[fareletiscool]

The water fills the gaps in the scarf and hold the rest in place

[SuperLoveyahh]

The air pressure outside the glass is more powerful than the air pressure inside the glass. When the towel covered the glass the air inside the glass was lock in. Therefore the water will not fall because the air pressure outside is preventing the water from falling into the ground.

[TheLordOden]

(continued)

The handkerchief acts as a means of support, because water is a liquid and subject to fluid mechanics...i'll stop here so that i don't bore everyone with an impromptu physics lesson :P

[TheLordOden]

see, it's this great thing called air pressure. Just looking at the glass, i'd say that the area of the opening is about four square inches give or take a bit. now, the pressure of air is about 6.7 kg/ sq. in. multiply that by four, and you have about 26.7 kilograms supporting that water. now, the weight of water is 15 kg/gal. since he only poured perhaps a cup of water into that glass, the water in the glass weighs only .93 kg, less than 1/26 of what the are is able to support.

[Arvak777]

Pressure? Almost when you have a straw with water and its covered on one side? Just a guess

[AppleTechChannel]

nobody's hating...this is just a lame trick that I learned in preschool.

[asdf8926]

you can do this with a full cup of water and a note card.

[gogo5565]

the air takes up the space

[xpinkgrizzlex]

There's so many dislikes because some idiots thought they were gonna see magic -_________-

[gunsandyoga]

Is this the same nerdy guy? Looks like he's been work out! Way to go!

[Hamadq8ybarca]

use a paper

[Truthiness231]

Can also be done with a wire mesh or a playing card or anything else that doesn't have space greater than the surface tension of water allows.

[WakingLife55]

Why are there so many dislikes?

[jacobblack18]

117 people did not come to their own conclusions.

[EVILdemon1123]

Surface tension and suction

[xXMrPatrick1207Xx]

The water fills the spaces in between the fibers causing the surface tension to hold the water in place. There is no trickery, just middle school science.

[LikeABoss062]

Is anyone else the 301 viewer...???...but there are 236 likes and 161 dislikes doesn't make sence...lol  this happens all the time.

[marradj]

You can do it with a peace of paper, too

[danielcarmi305]

Water's properties of cohesion and adhesion turn the fabric's holes into a kind of film, then the atmospheric pressure holds the air-tight fabric against the glass.

[closetmonkey15]

THIS IS WITCHCRAFT

[KreoD15]

Not only the airpressure but also the adhesive proporties of water make it possible to turn the glass.

[WangCinema]

@KreoD15 capillary action bro

[unamaxify]

i can do the same without the towel

-> freezer

[ejp93]

something to do with surface tension.

[MarcA229]

@cooljmex theyre all haters thats what they do haters hate

[qezart]

A bit of the water gets trapped in the fine holes in the mesh by the force of surface tension and it is able to hold up the rest of the water if there isn't any unfilled gaps in the mesh.

[HishowProductions]

I tried this, unfortunately i couldn't remember how to do it and i brought my laptop out to remind me. Well I did it, and i was so thrilled I was hovering it over my head, the dogs head, the tv, the radio and then my computer, long story short i need a new computer.

[DanoninoBG]

You want anti-gravity water?? Follow these steps:

1) Wash your hair. Wait till it is completely dry.

2) Brush it with a plastic comb. Stop when you hear it making "electric" noises.

3) Open the tap and let a very little stream of water out.

4) Place comb near the water

6) ?????

7) PROFIT!!

PROTIP: This will work better if your have curly hair.

[sprusegoose]

@DanoninoBG LOL!

[TheBrad95]

CoolStoryBro

[cleicsioluek]

It's the air pressure that fights against the water's pressure. Wow, I actually listened to my chemistry class!

[vctop101dunk]

anti-gravity? The water is still in contact with the handkercheif... It's just like... water trapping in the sink... (sink is the handkercheif in this context)

[rikard92]

the controll in this video was inverted to.

[phantomhockeyzero]

.. i dont get it.. where was the anti-gravity water?

[AceAndyman]

Its call surface tension. thats how it stayed up

[stricknacco]

The air pressure pushing upwards keeps it there. And there is no space for water to sneak out and thus equalize pressure, so it just chills.

[Froridinator]

So is it a scarf or a handkerchief?

[SumoSushiHAI]

Gotta love gravity

[CigaretteScars]

wheres my upwards flowing water? O_O ohh you sneaky....

[tigerlily7898]

why the dislikes?

[NeonGamePlayz]

@tigerlily7898 because of the deceptive thumnail it looked like up flowing water

[caroegc]

I was listening to The Kids From Yesterday by MCR and the beats fit perfectly with the What you need bit o.O

[imacanoli897]

103 people don't appreciate simple science.

[MagicallyFat]

Congratulations, you just got accepted into Hogwarts School of Witchcraft and Wizardry!

[xdoomedx14]

is like a suction cup on side outer of glass

[sotiris997]

@xdoomedx14 Not exactly. What happens is that the air pressure on the bottom side of the handkerchief is equal to pressure of the water on top of the handkerchief.

[MythOfEchelon]

"Here is what you need: wine glass, handkerchief, water, bowl, adult supervision. Place the scarf over the wineglass..." What?! :L:L

[CormacC95]

The water goes though the hankerchief, then you pulled the hankerchief up creating tension.

When you flipped it the hankerchief the tension stopped the water escaping the glass.

[willsgotbeer]

surface tension.

[Ahmedbilal09]

air pressure

[Rak27297]

You should totally be my science teacher..

[cooljmex]

why so many dislikes?

[bluebobdopepants]

@cooljmex i think there monks XD

[RaiYami]

@cooljmex cuz they probably tried this and failed or trolls

@cooljmex because they failed
