Trick candle

A trick candle is a novelty candle capable of relighting itself. By igniting magnesium inserted into the wick of the candle, the paraffin vapor given off when a candle is blown out can be set alight, allowing the candle to reignite itself.[1]

Trick candles were banned in Canada in 1977.[2] They present a fire risk in that consumers may throw them into the trash believing them to have been extinguished, only for the candles to relight.[3] A spokesperson for the National Candle Association recommends immersing the candles in water for a while before discarding them.[3]
