Science/Notes:

What is happening is the flame is causing the air particles inside to expand away from each other. this is happening because the dioxegen (O2) is expanding to become less dence and into a lighter gass. When the flame goes outthe air contracts again and causes the jar to seal against the plate. 

It works worse without water :)
