Strike a light! A match bursts into flames after being struck. This match, of the 'strike anywhere' kind, consists mainly of phosphorus sesquisulphide and potassium chlorate in the head. When the head is run across a rough surface, friction heating allows an exothermic oxidation reaction to take place. The excess heat developed is sufficient to ignite the wood of the match stick.
