Radiometer
Radiometer
A little spinner powered by nothing but sunlight. Set it near a window and watch the vaned wheel turn as light hits the dark and light wings differently.
- Alternating dark and light vanes that spin in sunlight
- Stronger light means more energy and faster motion
- A genuine thermodynamics demo for ages 8 and up
- Small 3 x 3 x 5.5 inch glass bulb
Editor's note
A classic windowsill desk toy that doubles as a sneaky science lesson. Great for a curious kid or a fidgety adult.
