Steve Spangler Science: Stuck Like Glue (Air Pressure Trick)

Simple air pressure difference is all the glue you need to lift a plate with a jar.

This activity is a great way to reveal how air pressure differences cooperate. An airplane flies because of these differences cooperating but you can’t see them at all. They’re out there working under and over the wings somewhere. Here’s a way to hold the results of this cooperation in your hands, up close, and get personal with it. A flame and some wet paper make fast friends of a jar and a dinner plate. Science is so cool!
