The Chinese Invented It: Gunpowder & Fireworks

Gunpowder is one of the Four Great Inventions, along with the compass, paper and printing. These inventions are celebrated in the Chinese culture for their historical and far ranging impact.

Invented in the 9th century, the chemical combination for gunpowder was discovered searching for an elixir for immortality. The alchemist mixed saltpeter with charcoal and sulfur (and honey), and this mixture exploded when exposed to a flame, burning down the house in which the experiment was being done.

By the 10th century, this discovery led to fireworks and firecrackers, used during many celebrations, often to frighten away evil spirits. Gunpowder was also used to create various weapons, such as bombs, landmines and flamethrowers. They also used it to fight the Mongols in the form of miniature exploding rockets propelled toward the enemy.

Here's a short video created by SciShow that explains the science behind gunpowder (in an entertaining way):



So next time you watch a fireworks display, or enjoy playing with sparklers - you can credit the Chinese. 





You can also make decorative firecrackers with instructions on our earlier post here.

  1. My two year old has not liked the 'naughty bangs' (as she calls all the fireworks which have been going off every night here just recently - it's Guy Fawkes at the moment over in the UK and is very noisy until very late at night!)
