  • Watch in amazement as the vanes seem to magically spin on their own with this solar powered toy!

    When light strikes the diamond shaped vanes it tranfers heat to each one, but not in the same degree. The white side reflects the rays and the black side absorbs the rays, this action causes them to spin! The stronger the light the more energy there is to heat up the darker side causing the vanes to spin faster.


    Age range: Ages 8+
