4. Magnesium and Dry Ice ReactionWhen ignited, magnesium produces a very bright light. It's why handheld sparkler fireworks are so brilliant. While you may think fire requires oxygen, this reaction demonstrates carbon dioxide and magnesium participate in a displacement reaction that produces fire without oxygen gas. When you light magnesium inside a block of dry ice, you get brilliant light.

5. Dancing Gummi Bear ReactionThe Dancing Gummi Bear is a reaction between sugar and potassium chlorate, producing violet fire and a lot of heat. It's an excellent introduction to the art of pyrotechnics because sugar and potassium chlorate are representative of a fuel and oxidizer, such as you might find in fireworks. There's nothing magical about the Gummi Bear. You can use any candy to supply the sugar. Depending on how you perform the reaction, you may get more of an immolation than a bear tango. It's all good.

7. Sodium and Chlorine ReactionSodium and chlorine react to form sodium chloride or table salt. Sodium metal and chlorine gas don't do much on their own until a drop of water is added to get things going. This is an extremely exothermic reaction that generates a lot of heat and light.

10. Sugar SnakeMixing sugar (sucrose) with sulfuric acid produces carbon and steam. However, the sugar doesn't simply blacken! The carbon forms a steaming tower that pushes itself out of a beaker or glass, resembling a black snake. The reaction smells like burnt sugar, too.
