Different colors of LED light illuminate a small corked test tube of hydrogen and chlorine gas with no reaction; ultraviolet light causes an explosion that shoots the cork across the room. The gas mixture is made by the electrolysis of hydrochloric acid 8M. A water bath allows for filling the tubes under water. The tubes are quartz.
