Candle wax is flammable as a vapor, so a candle can be relit by igniting the smoke trail of a recently blown out candle, which contains wax vapor. This can be used to demonstrate how caution needs to be taken with flammable vapors.
1. Light the candle
2. Blow out the candle
3. Relight the smoke trail
This works best with a candle that has a large wick.
Caution should be used when handling matches and goggles should be worn at all times.
