Heebie Jeebies Crookes Radiometer - 18cm Glass Solar Powered Light Mill for Science Experiments & Home Decor

Product Description

In a world where energy is scarce, we’re relying more and more on the sun for power. But how does it work? The Crookes Radiometer can show you in real time the impressive power of light.

The vanes inside an airtight glass bulb rotate when exposed to light, spinning faster as light gets more intense. It’s real life thermodynamic science in action, without any of the hard work or complicated stuff – just stick it under the sun and watch it spin!
