Key item features

  • Modeled after Crookes Radiometer with white and black vanes, stands 6" Tall.
  • When placed in the Sun vanes will move based on Thermal Transpiration.
  • Changes of temperature of the gases inside create an unequal balance in pressure on the black side and on the white side of the vanes.
  • Vanes are pushed into the area of lower pressure. Gases must always find equilibrium, so the radiant energy causes movement of the vanes.
  • Made of hand blown Glass (very fragile) and vacuumed sealed. For ages 14+
Current price is $19.99
Price when purchased online
  • Free 90-day returns

Solar powered

I remember having one of these when I was a kid. Just a gadget but neat to watch, powered by the sun or a bright light. Hoping my grand kids will enjoy it and get more interested in science.

Yes, it's safe to order this

Considering how fragile this thing is I was amazed that it arrived unbroken. Yes
