Screaming Jelly Babies

This demonstration, from whynotchemeng, involves putting a jelly baby into molten potassium chlorate. The reaction shows the oxidation of the sugar in the jelly baby. Sometimes a high pitched screaming noise can be heard during the reaction. Jelly babies can be used since they have a small enough surface area that the reaction can take place at an appreciable rate, without being explosive.
