What.The.Fuck.....

@chantaclear When he heats the vial, the gas inside expands. Then when he places the vial over the tub, the gas inside cools off, so it contracts. When it contracts, the pressure inside the vial drops. At that point the pressure outside the vial is greater than the pressure inside the vial, so whatever is outside of the vial gets pushed inside.

HAHA... it farted

@chantaclear Yes, it is the outside air pressure being higher than the pressure inside the flask.
The air outside is pushing the material into the flask.

@christoph2005 Wait no, it's just expansion, right?
-
@christoph2005 So it's air pressure?
-
it farted, wow..?! xDDD

O.o Water can make MUSIC? >___<

He TOOTED! what a NERDDDDDDDDD

Simply speaking, it's not amazing in the least. It's a well known phenomenon.
It all has to do with air pressure. The heated flask has less air pressure due to the heated air inside. As it cools, in the water, the air condenses causing an area of less pressure (essentially a partial vacuum). The difference in air pressure inside the flask to the air outside it, causes the water to raise up due to the pressure of the outside air, compared to the pressure inside. It's an old experiment.

There's not enough characters in youtube for me to explain fully what happens here but basically the heated flask has fewer air particles than a room temperature flask. When the flask cools it creates a suction.
But someone will read my post and tell me I'm wrong but I assure you, that's what's happening here.

ya, you're right, but maybe i can explain it better.
there are less particles in the heated flask because heated particles are farther apart. so when the flask cools off, the particles move closer together. since the particles are getting closer, the bottle needs to be filled with something, so it pulls the water up into the flask =]
i understood you, but it wouldnt make sense to some =]
