    A great explanation of the power of vacuum /negative pressure.
  • @Xsais18
    why does he remind me of patrick bateman when he speaks so enthusiastically
  • So if the lid area was 1m² , 8000 KGF wouldn't be able to take the lid off?

    The frozen water molecules expand causing pressure, the water that is unfrozen is pushed out because the space it then occupies is smaller than the same amount of molecules would have if the whole bottle were thawed.

    wait, if you suck all the air to create vacuum, why doesn't it crush? do they just suck enough air so that it's way less dense, but not enough for it to crush or break?

    Does this mean a suction towel hanger wouldn't work in space ?
