i may be wrong, but i think i noticed the liquid became less clear after every pour. i skipped from the first frame to the last and i got the impression the shade was darker.

he doesnt refill three cups... he refills FOUR cups...

This is very obvious.

The three larger cups are already filled with water or a very low density liquid. The original liquid has a very high density, looks a bit sticky. Notice at the beginning how the contents of the first cup flow ? As he pours the high density white liquid into the second cup, it flows to the bottom of the second cup giving the impression that it is empty. In reality, the white liquid is heavier than the transparent liquid already in the second cup. However both liquids are miscible and he ends up with a slightly less dense mixture of both white and transparent liquids, giving you the impression that the volume has doubled. See how easy the liquid flows when he pours the contents of the third glass into the fourth? By now, the original sticky liquid of the first cup has been diluted many times and is less dense than at the beginning.

He is clumsy, he could take his time and the trick would become less obvious.

#3, #1 is right. Switch between 0.10 and 1.20, you'll see the difference.

using a particular liquid that creates a lot of foam, just like when you shake a coke etc, each time he pours, it creates more foam ontop, liquid stays the same, the foam gets more and more..

#5 am i the only person who sees 4 larger cups not 3?!

but i do agree with your theory, this is why he uses the patterned glass, not plain

0:39 watch the top right of the largest glass, you see the clear liquid wobble

seems your right #5

#5 is probably right. it would account for the change in shading. it's what i figured at first but i couldn't see the water at all (or whatever liquid he's using). but i guess that's why he uses weird looking cups that aren't smooth.

There is a clear tube within all the cups but the 1st one, the last one is filled with a clear liquid the others are capped off, the tubes come up to about 2.5cm before the top of the glasses so you cant see them from the angle its filmed at, however if you look very carefully they create a different colour on his t-shirt if you look through them at it.

Am I the only one that can see the ice in the glasses? The white stuff must melt the ice really fast. Obviously there is a clear liquid in the glasses as well.

Look VERY closely @1:25 and notice how he makes absolutely sure that the cups DO NOT MOVE at all. But at 1:25 he accidentally pushes it and if you got good eyes you'll see that there is already some liquid in there.

at least thats what i see

Here's how it's done:

(#11 is almost correct, but 'all' the tubes are open.)

Inside each glass (except the smallest) is an open ended tube, full of clear liquid. Since the volume of the tube detracts from the apparent volume of the glass, it fills up with a smaller amount of liquid. Notice how he is careful to pour very close to the rim of each glass, instead of straight into the centre as would be more normal.

When the contents are then poured into the next larger glass, the additional contents of the tube are poured as well, so the amount of liquid increases each time. The contents of the final glass are now easily sufficient to fill every previous glass.

Actually I had a magic set long ago with this trick in it. The cups have a mirror inside of the down the center of the cup except for the first one. the mirror makes it look like the cup is whole but depending on where the mirror is placed you can fill one side of the cup with less liquid. If you look carefully especially at the last cup you can actually see the top f this piece of miror near the rim of the cup. This is also why the cups have that diamond pattern on them, to obscure people from seeing a clear reflection.

Duh.... look at 1:09. the cups are all filled with fluids in the middle. almost like there is a tube in the middle for like a shot of something. if you watch him he pours all of the fluids in the side of the cup almost on the rim. NEVER in the middle. if he did it would fill up the middle part first and cause his trick to flop. >:)

i agree with the tube theory from #11 if you look closely at the glass he is pouring from at 0:21 you can see a circle thats the top of the tube

I think it's done with hot saltwater. Inside every glas is a cone of ice. You can see the ice at 0:45. Both temperature and salt melt the ice quickly and that way the liquid seems to get more and more.

#1 Good observation. But it has to do with the cups. There is a cup inside of a cup, and he pours it down between the two.

Keep it simple guys, you can obviously see the milk diluates in each transition. There's water in the glasses.

using Einsteins theory of relative velocity, the liquid he is using is compressed CO2 in a liquid state combined with room temperature liquid nitrogen. every time he pours the solvent into the other cup Nitrogen from the Air dissolves into the mixture increasing its relative mass and volume.

I love how NONE of the comments are right :P

The secret is in the liquid itself ... there are no other tubes, liquids or a cup inside another.

Good luck with it ;)

No great mystery here - although there are several ways to achieve it.

In theatre and tv, there are double surface glasses. The glass volume is not as much as you think. This enables actors to "drink" beer without getting drunk.

Or, the glasses can have transparent objects inside.

Notice the glasses are slightly frosted. This helps the illusion.

You can clearly see that there something in those glasses. Especially at the largest glass, when he puts his hand behind the glass, you can spot the surface line of the liquid. It seems that he is doing it with milk and water or something like that.

First off, #34, liquid nitrogen is no longer a liquid when it reaches room temp. wikipedia - "liquid nitrogen boils at 77 K (−196 °C; −321 °F)" Second if it were CO2 and Nitrogen it would be "foggy" above the glasses, he would have to wear gloves or he would have instant frost bite, the liquid nitrogen would cause the glasses to crack and most likely break.

Now for my explanation. #31 has the best evidence of the tube theory at 0:45. This trick is done with tubes. As for the liquid. I believe it to be something like salt water and at the bottom of each glass there is salt or some other solution. It could also be that there are two chemicals present that cause a precipitate. they use this formula in the example and it forms a precipitate that looks much like the liquid in the vid.
AgNO3 (aq) + KCl (aq) → AgCl (s) + KNO3 (aq)

But it could be as simple as salt water. However the tube theory is definitely used.

if you look closely at the second glass as he fills the third glass with it, you'll see the ring of the inner tube in the glass. Like it's already been said, it seem that there are tubes in the middle of the glasses each with their own liquid. :)

Sorry to disappoint the elaborate theories that sound so certain. The is no trick. Each NORMAL glass has a small amount of white powder on the bottom that is a super-absorbent polymer. See it? It expands like crazy in water. I used to do this all the time with my chemistry class.

Another example is to pour water into a opaque coffee cup and turn it upside down and nothing comes out! Looks of amazement. Where did the water go? Again elaborate theories as to the fake glass, etc. It all due to the simple white powder you can buy.

By the way, they've even used it in diapers. It's made from a type of corn starch.
