Working with gunpowder is a potentially dangerous activity because of its explosive and propellant properties. Would we be able to produce a colorful — and controlled — firework display on the Rough Science island? Gunpowder consists
of an oxidizer, 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, firecrackers (bangers), Roman candles and pinwheels (Catherine wheels). | ||
