Glow In The Dark Duct Tape

Just sticking together and then pulling apart two pieces of duct tape will cause them to produce a blue line of light in an effect called triboluminescence.What's happening is that the action of pulling apart the glue causes charge separation in the two strips. The charges then attempt to recombine and collide with nearby molecules (of tape, glue, or air) exciting them and releasing light.All you have to do is stick 2 pieces of duct tape together and pull them apart.
