A flame reaches a small container of gunpowder. The gunpowder ignites, releasing large amounts of energy. This causes the molecules in the gas which the combustion of gunpowder produces to move faster. Pressure increases until the container bursts open. Air around it is pushed away as white hot gas escapes in a flash of light, causing ripples of air to spread out from the firework. It is these ripples that the ear hears as sound.
