This is a very extreme experiment that I believe many students would love to watch. A gummy bear, which is comprised mainly of sucrose, is added to a test tube of potassium chlorate. The reaction between these two ingredients is a very intense, exothermic reaction that gives off a huge amount of fire and heat. I would use an experiment such as this at the start of a class on enthalpy or exothermic reaction to help my students understand how an object they've probably seen everyday could be involved in an impressive scientific reaction.
