Description

It has never been more fun to learn! Engage children of all ages with STEM toys that will encourage them to explore, understand and be inspired by the world of science, technology, engineering and math. 

This radiometer is a fun, vivid way to demonstrate heat transfer!

The wings in the radiometer are alternately dark and light. When the light strikes the wings, it transfers heat to each one, but not at the same degree. The light wings reflect the rays and the dark wings absorb the rays. As the light gets brighter it creates more heat and spins the wings faster.
