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.

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! 3 Years + Show more
