Small, very portable, and easy to setup. This is the most cost effective light mixing demonstration we could find for you!

Demonstrate refraction, reflection, color, and color mixing with these low cost and easy to use light sticks. Each color box is magnetized, allowing you to mount them on chalk boards and other metal surfaces. Use with a set of lenses and mirrors (sold separately), and you will have everything you need to:

• Create single or multiple parallel, convergent or divergent beams
• Study color mixing
• Create and test complex light paths from theoretical layouts
• And much, much more

Includes 3 light sticks: red, blue, green LEDs. Requires 6 AA Batteries (included).
