Original Purpose: Freshening your breath.
Aha! Use: Holding birthday candles. Make sure you buy the original rolls of candy for a snug fit. (The LifeSavers sold in big bags are slightly larger and don't work as well.) Secure the candles inside the candies, then place on top of the frosting.
Reward: Holey salvation! No more puncture marks in the tops of your cakes.
