Create Light with the Power of Water

Spectrum Tubes demonstrate the wave properties of different gases.

A fun tool to help teach water concepts.

This safe spectrum power supply features encased spectrum tubes.

A mess proof way to demonstrate waves and refraction in water.

Ideal for investigating the reflection of light at a plane mirror and at a water interface.

The Bottle Rocket Launcher uses the power of compressed air and water for liftoff.

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

This Fan Cart demonstrates Newton’s principle of action and reaction.

Classical demonstration of refraction and internal reflection.
