Glow Sticks From Scratch

From BoingBoing, a fascinating video on the chemical components that are used to make a glow stick. It's better than your average mixing chemicals video (of which there are a surprising number on youtube) because the video's chemist explains a key point in understanding the reasons that the reaction works. Two different reactions are taking place; one which generates energy (but no light by itself) and the other which turns that energy into the visible fluorescent light you see from a glow stick. ]
