Fisher Bay Observatory Gallery

Included with museum admission.

Note: Capacity is very limited; seating is on a first-come, first-served basis.

Join us for four classic activities that play with motion.

Tops
Tops come in all shapes and sizes. Use various building materials to experiment with different spins. Making tops was one of founder Frank Oppenheimer’s favorite activities.

Benham’s Disks
Rotate a black-and-white disk at the right speed and the pattern appears to contain colored rings. Try spinning the disk more slowly or in the other direction. Do the colors change?

Rotocopters
Rotocopters are a cross between spinning maple seeds and modern propellers. How far can your copter fly?

Paper Planes
Paper plane designs range from simple to complex. Experiment to find which designs fly the farthest or perform the best tricks.


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.
