Dr Peter Wothers explores the properties of fire with three Key Stage 3 students at his laboratory in the University of Cambridge鈥檚 Department of Chemistry. The team begin by igniting a balloon filled with propane, to visually explore what happens during combustion. Next, they examine what makes up a flame, and measure the temperature of different parts a Bunsen flame. Finally, they mix different ratios of propane and oxygen in balloons, before igniting them and measuring which ratio produces the loudest bang.
