You can see the water freeze right before your eyes in a vacuum

  • Was that it freezing at the very end? It doesn't make sense that water would freeze in a vacuum, it would boil, to expand and take up the space... at last that's what I've seen happen before.

  • Basically, when you remove pressure, you are increasing evaporation of the liquid (boiling). When you keep pulling a vacuum, you are lowering the 'energy' of the water. And when that energy gets low enough, the water is unstable as a liquid, so it freezes.

  • This video would have been a whole lot cooler if there were sound... or narration... or a decent explanation of what was going on.

  • bitch.

  • hold camera still

  • agree

  • the thing "icedz" forgot to explain is that there is no direct energy in water, there is ofcourse themal energy, im not sure if there is kenetic energy pretty sure theres not, but it freezez because it was never actually at room tempatuer and taking less molecules from the thermal energy makes it more dense causing it to freeze

  • Okay, so partial vacuum = boiling, more vacuum = freezing.. gotcha.

  • it does boil in a vacuum. but boiling is a cooling process
