Underwater Fireworks: Chlorination of Acetylene
Description: Chlorine gas is generated from bleach + HCl in a flask. The chlorine gas is bubbled into the bottom of a cylinder of water to which calcium carbide is added. Flashes of light are given off in the cylinder where the acetylene bubbles and chlorine bubbles react. A second version reacts at the surface of the mixture, producing a retort and carbon.
