air pressure
Beakman challenge: Pick up a jar without touching it. Light a napkin and put it inside of a glass jar. Quickly place an infalted balloon on top of it. The balloon will partially be sucked into the jar due to the change in air pressure so you can pick up the jar by the balloon and not be touching it.
