Air cushion plate using balloons
The set consists of five air cushion discs, five balloons and five stoppers. When a balloon is inflated and placed on the disc, the air is gradually released, creating an air cushion that lifts the disc slightly off the surface. This significantly reduces friction and allows movement to be observed with almost no resistance.

Air pressure and vacuum kit
This air pressure and vacuum set is used e.g. for demonstrating the effect of air pressure on the boiling point of water, the size of a balloon in a vacuum, and the holding power of a suction cup.
It can also be used to show that air has mass and that sound cannot travel in a vacuum. A plastic syringe and a one-way valve make up an affordable vacuum pump .
The set contains 10 experiment instructions, which can be given directly to students.
