All Ages

Join us for four classic activities exploring color and light.

Light Boxes
The wondrous cousin of the kaleidoscope, the Light Box uses curved mirrors to create patterns of lights and colors from the environment for the maker's enjoyment. See how this toy changes your perspective on the world around you.

Spectroscopes
Not all lights are made the same but all are equally fascinating. Spectroscopes allow the curious observer to examine the colors present in a light. Is there a difference between the sun and lights in your home?

Scan Scopes
When you look through a narrow slit, you can see only a thin strip of the world around you. But move the slit around rapidly and your eye and brain combine these thin strips to make a single complete picture.

Benham's Disk
Rotate a black-and-white disk at the right speed and the pattern appears to contain colored rings. You see color because different color receptors in your eyes respond at different rates.


Use everyday materials to create models and other tools for exploring the world around us. Run by a highly skilled, dedicated team of volunteers, these drop-in workshops mix classic activities with open-ended investigations, encouraging participants to follow their hunches to aha moments of scientific insight.

All materials provided; take what you make.

Explorables has been offering science to go since 1990.
