Geissler tube
A Geissler Tube from my collection of odd bits and pieces. The grand daddy of the neon light, it glows as electricity goes through the tube, The purple is where there is ordinary glass and the green is because it has Uranuim glass which is not radioactive but fluoresces a lovely green.
