This is one of Paul Hewitt's favorite demos for atmospheric pressure!
A simple design that demonstrates a powerful concept: Atmospheric pressure! It's like the mat is glued down! Use a flat lab stool and you can lift the stool! A great way to show that suction cups stay stuck because of the pushing force of air, not from a pulling "suction" force. Measures 10.5" x 10.5".Products being sold are not toys. They are for Educational / Laboratory use only. They are not for use by children 12 and under.
