Spit Take "Amazing Water Trick! How to Suspend Water Without a Cup!"

Wonder how many people have flooded their kitchen trying this one

I'll have to keep that type entertainment in mind when I design my next kitchen. That's very cool.

But, is it real? I mean, it looks real. I just never thought you could do something like that.

Not real, not possible. If the water is actually rotating (the twist in the glass removal) then it is even more inclined to disperse through centrifugal* force than to stay together.

Lets see: It violates every single possible law of physics so... no it's not possible at all.

First, the way water tends to stay together is through hydrogen bonds. This is how you get little beads of water on your counter that don't disperse. But in a larger volume gravity and mass are far more powerful. So it can't be hydrogen bonds that are holding this formation together.

Second, the water is actually spinning. Think about this: when you go around a turn really quickly, your body continues in that other direction (or it wants to). This is called centrifugal force. Since we've already established that there is no force acting on this water that could possibly keep it together, the spinning makes it even less likely the water formation wouldn't simply collapse and splash all over.

Very, very obvious fake.

It seems as though it is pretty impressive special effects though. Obviously it was meant to showcase the creator's talent. And play a little trick on the people who aren't too familiar with physics

Possible, if you use a different form of water.

Ice.

Distilled works better because distilled freezes clear. The minor spillage at the beginning is a tiny bit of melting to loosen the block of ice.

I was thinking the same as Casey. Though I figured put in the freezer just long enough to get a slight layer of ice on the edges, and bam, magic.

But it looked really cool and would love to be proven wrong.

Not possible, I say.

Except if you're a waterbender, of course.

Well, it's a very cool trick, or effect. I like it.

Comment: Check out this fancy "trick" using a glass of water. It looks incredible
and would, naturally, lead folks to attempt it. I think itís fake, thereby causing
countless fools to dump water all over their floor in an effort to repeat the
trick. But if itís fake, how is it done?

I think it might work with the ice theory. I wonder if you froze just a thin outside layer if it would work. Hmmm sounds like a fun experiment. May try it and let everyone know later.

The guy who made the video (according to the end credit) appears to specialise in CG.

I'm sure someone mentioned this before (and I'm sorry I didn't read all the comments) but I contend that the spinning force would actually make the water disperse faster. I call fake as hell. And for those of you who remember my "Glowing tomato" debunk I did for the boards, NO, I'm not doing this one =P

Nice illusion. Maybe ice, but more likely something dissolved earlier in the water, like clear gelatin. Must take a lot of tries to get it just right. I expect someone accidentally discovered this trick while making jello shots.

The first trick to this is to keep the jello mixture in its glass upside-down in the freezer long enough to get a thin shell to harden around the (colder) glass, but not so long that the remains of the jello mold shell will noticeably survive when you break it later. Incidentally, while in the freezer the bubble of air at the top of the glass will contract with the lower temperature, creating a partial vacuum that will help keep the mixture from falling out while you're moving it to the counter.

The second trick is to allow the glass to warm just enough so that the thin shell easily slides off the inside of the glass, but not long enough so that it won't survive for a few seconds once you remove the glass. By watching carefully you can probably see the moment when it loosens from the glass and slides the few millimeters to the surface of the counter; that's when the turn on the video camera. Then you'd better act quickly – you may have only a few seconds before it gets soft enough that the whole thing falls apart when you remove the glass (as we saw in the video).

I believe it's done with the help of clear gelatin mixed in the water, and a freezer.

D'oh!

I agree with the sentiment that no matter how they manage to film it (CGI, or something like the gelatin technique), it's a trick to see how many make fools of themselves trying it themselves.
