  • I am glad that he uses safety goggles. Imagine if a splash of water would have entered his eyes!

  • Rather than tip the inverted jar with the screen lid, take a pump-spray bottle and fill it with some soapy water. Then spray the screen of the inverted jar. That will break the surface tension and make the water flow out. This is because soap molecules interfere with water's hydrogen bonds.

  • this is wrong ...surface tension plays no role in keeping the watre inside glass ...it is still due to atmospheric pressure
