Fireworks were first invented in China over 2000 years ago. The first firecrackers were chunks of green bamboo, when put with fire it causes the bamboo to make loud cracking sounds. Because of the way Bamboo grows, it allows for air pockets to form inside the plant’s segments. Once heated up, the air inside the bamboo expands which causes it to crack through the sides which produces the cracking sound.
