This air pressure and vacuum set is used - among other -  for demonstration of atmospheric pressure on the boiling point of water, the size of a balloon in vacuum, and the holding force of a suction cup. It can also be used to show that air is massive and that sound can not travel in vacuum. A plastic syringe and a one way valve make up an affordable vacuum pump.

This set contains 10 experimental guides that can be given directly to the students.
