Rainbow Skytop

A fun, hands-on way to demonstrate physical science concepts and an absorbing outdoor activity, too.

This solid wood, hand-powered mini-propeller could complement explorations of physics (hand-to-rotor energy transfer), botany (models a maple seed in flight), and mechanical engineering (models a helicopter rotor).

A quick spin sends it twirling. Sanded smooth with an 8" wing span on a 7½" stick.
