"bouteille de gaz"

The Handheld Discharge Electrodeeasily and safely discharges an electrostatic generator.

Graphically illustrate the fact that like charges repel each other.
The multi-colored ribbons are connected to a suction cup that sits on top of a Van de Graaff generator. As the generator operates, the ribbons accumulate a charge and stand on end.

Create Dramatic Electrostatic Effects

Students of all ages love dice games and you'll love the simplicity with which you can review number facts, teach random numbers, explore probability and much more. These traditional-sized dice come in all white or multi-colored.

This generator can perform all electrostatic experiments on a spectacular scale.

Get hands on with dew and condensation.

Demonstrate the combining volume ratios of gases.

The Density ID set offers hands-on learning on the concept of density.

Demonstrates the relationship between mass and volume.

Investigate the dependence of pressure on a gas with changes in temperature and volume.
