Crookes tube with a Maltese Cross.

The tube demonstrates that electrons go in a straight line and don\’t go through metal. The cross can actually lay down and stand up (mechanically). When the cross lies down, the glass face of the tube emits a green glow when the electrons strike the glass wall, when it\’s right up you will see the shadow of the cross.
