A fire snake, also referred to as a black snake or sugar snake, is a classic science experiment you can do right in your own kitchen using a baking soda and sugar mixture and a fuel to ignite the reaction. When the baking soda gets hot, it makes carbon dioxide gas. The pressure from this gas pushes the carbonate from the burning sugar out, producing the snake reminiscent of popular intumescent fireworks.
Rain Drops by Evan Gant. All this concept needs are plastic bottles, a structure, and gutters, which catch rainwater.
