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.

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

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

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

A perfect tool for studying density, specific gravity, and water displacement. The 250mL polypropylene overflow can with spout only requires a catch bucket for the overflow.

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.

The refraction tank with laser provides excellent visibility!

Efficiently illustrates the various types of diffraction.

This laser ray box is adjustable, magnetic, and bright enough to use in ambient light.

This is an excellent and economical set for introductory ray optics.

The Capillarity Apparatus is intriguing demonstration of molecular attraction.
