Chandelier Moves in the Light: Gotta-See Video

A radiometer is a way to measure electromagnetic radiation. They've been around for over a century, but you've never seen them like this. Radiometers are sometimes used in science classes to illustrate to students how light can move objects. The energy of the light is able to move the vanes inside the partial vacuum of the radiometer.

Artist (and science geek) Luke Jerram created a beautiful chandelier using radiometers for the Bristol and Bath Science Park in England. The chandelier is activated by the sun streaming thorough the windows, and makes a soft clinking sound as the radiometers spin. via Luke Jerram
