Why do balloons make a loud ‘POP’ noise when they burst? What is the motion of the bursting balloon?
When the balloon is blown up and expanded, the rubber stretches causing the shape to differ from the original. Under this condition, the balloon can withstand a very high elastic energy pressure. When the balloon that has expanded is poked by a sharp object, the balloon explodes and splits into rubber fragments. This phenomenon is caused by the hole on the surface of the rubber, which expands and forms a long slit. The bursting balloon which creates the small hole then stretches into a long slit, requires a small amount of elastic potential energy that has been stored by the balloon. The rest of the remaining energy is transformed
