Trick candles

Trick candles are a novelty candle often used at children's birthday parties. These candles relight themselves, using a fuse similar to those in dynamite sticks, the principle being that by igniting magnesium inserted into the wick of the candle, the paraffin vapour given off when a candle is blown out can be set alight, and through this, the candle can reignite.

Despite being a principle shared with dynamite, these fuses are, however, much less dangerous, and are easily extinguished with water.

Trick candles are banned in Canada.
