Acetylene Explosion: No chemical demonstration presentation is complete without an explosion. Our philosophy is to keep demonstrations as simple as possible. Rather than carrying tanks of gas, we use calcium carbide to generate acetylene gas in a shampoo bottle. In this acetylene explosion video, we first show simple combustion of acetylene in a beaker then we do an explosion in a more confined volume. Acetylene has wide explosion limits; thus, calcium carbide needs only an approximate measurement.
