Upside down water glass trick.. IMPROVING A GREAT DEMONSTRATION

Improved versions of a classic demonstration, the simple water glass turned upside down has a new twist when a balloon is used instead of a flat card.. The seal is improved enough that the jar of water can shaken and spun around without the water being spilled out. The weight of water inside the jar causes a slight pressure drop inside the container and the cohesive attraction between the water molecules hold them together when turned upside down, with a lower pressure inside the jar, atmospheric pressure pushes against the covering, which in turn seals the opening of the jar so the water stays inside. This behavior would be similar to the action of a suction cup.

MISTAKE: maximum water column should be 33.9 feet which converts to 10.3 meters.
Absolute zero is usually referred to as a measurement of temperature, in this case the absolute pressure is zero meaning it is a vacuum.

I briefly removed this video due to some questions about the explanation of the cohesiveness of the water being required for this to work and replaced it with a 2nd version that had that part of the explanation removed. After running some additional tests, I believe that it is correct as stated. However, it is my theory and I value any additional explanations proving me right or wrong.

I have had quite a few additional questions regarding other variable in this experiment I will test additional ideas and present them in a future video.
