The Challenge: Make fireworks

How are firecrackers made?

A firecracker (banger) is probably one of the most powerful fireworks because the entire contents explode at once. While the contents of most other fireworks go off bit by bit, in a firecracker the whole lot is packed into a single cardboard tube.

The fuse ignites this and the explosion shoots out of the end of the tube and into the air. The effects are not only powerful, they are sudden, and occur from ground level upwards.
