Lisa and Josh make a candle relight as if by magic. They investigate how long it takes for a covered candle to go out, and find out why a candle can keep burning for a longer time in a larger jar than in a small one.
In this fun, free science experiment to do at home with young children, Lisa shows Josh how to relight a candle without touching the wick. When a candle is blown out, the wick stays hot, and wax continues to be drawn up through it before evaporating. This wax gas above the candle can be relit, meaning that a flame will appear to jump from Lisa’s lighter to the candle wick.
Josh times how long it takes for candles to go out when covered by different sized jars. A candle flame is the result of a chemical reaction between wax gas and oxygen in the air. When you trap the candle in a jar, it only has a limited amount of oxygen. Josh finds out that in larger jars, there’s more oxygen so the candle can keep burning for longer, but that the flame will eventually go out.

This series of ExpeRimental is supported by the Royal Society of Chemistry.
