What You Need Gummi bear candyPotassium chlorateLarge test tubeRing standBunsen burner or other heat sourceTongs Here's How Set up a large test tube over a heat source, such as a bunsen burner. Add a small amount of potassium chlorate to the test tube and heat it until it melts. The exact amount isnt important... aim for a small scoop.Using long-handled tongs, drop a Gummi Bear candy into the test tube.Its just that simple! The reaction between the sucrose in the Gummi Bears, potassium chlorate, and oxygen produces carbon dioxide, water, and potassium chloride. Tips Use proper safety precautions, including safety goggles and a lab coat. Be advised, the reaction is vigorous enough that the test tube may shatter. Adult supervision is required.The Instant Fire demonstration is very similar to the Dancing Gummi Bear demo.Another way to do this demonstration is to set the Gummi Bear on top of cold potassium chlorate. When you are ready to start the reaction, it can be initiated by adding a couple of drops of sulfuric acid to the contents of the test tube.
