These rockets shot rocket powered arrows from their mouths, and were used against the Mongol invaders of 1279. The principle behind these rockets is still used in rocket powered fireworks today (History of Fireworks).

What goes on when fireworks go off? Well it’s all pyrotechnics, which are chemical substances that produce light and smoke when ignited. Pyrotechnics are also used in flares, smoke bombs, explosives, and matches. An aerial fire work is a rocket made of a cylinder, chemicals inside the cylinder, and fuses attached to the cylinder. The chemical mixture that makes up a firework is black gunpowder, which is potassium nitrate, sulfur, and charcoal. When ignited this mixture makes a small explosion. Also when these three chemicals react with one another they produce carbon monoxide, carbon dioxide, and sulfur dioxide (How Fireworks Work). These gases expand...
