This video explains how gas particles behave and the result of gas particles hitting a surface, in particular the surface of a suction cup. How do gas particle collisions result in force, how do they result in pressure, and how can we experience that force?

GREAT!!! you make gases pretty interesting, something i did not know was possible. You are truly a teacher.

Another gem. Loving the butcher knife used for the cross section.

So; how are you lifting it up ?! ;);) THX !!!

NO WAIT! There's something wrong! When the pushed cup is flat on the table, it is at equilibrium, this means that the downward force of the air particles is cancelled out by the upward force from the table on the cup. Later, when you pull on the cup to lift it you are trying to overcome the force exerted between the cup and the table. The act of pounding on the cup is like attaching "springs" to the cup that will activate when you pull on the cup to lift it. In fact, the harder you pull, the larger this force gets!
