ELI5: Trick Candles

Well I turned 5 today and these motherfucking things just about ruined it for me. What sorcery plagues these firesticks to never cast my wish?

The wicks of trick candles have a small amount of magnesium mixed in so that it wont blow out fully when you extinguish the flame. It's still hot enough to reignite the wick each time you blow it out because magnesium ignites at a much lower temperature, and that catches the rest of the wick on fire.
