The challenge: Make Fireworks
Working with gunpowder is a potentially dangerous activity because of its explosive and propellant properties. Would we be able to produce a colourful - and controlled - firework display on the Rough Science island?
Gunpowder consists
of an oxidiser, fuel, and binders. When it burns, it quickly releases
a large volume of hot
gases. In firework displays, gunpowder is made to perform in different
ways such as rockets, bangers, Roman candles, Catherine wheels.
