Here’s a cool looking glow in the dark novelty candle from Happy Candles. The glow lasts quite awhile but needs to be recharged with light eventually. It burns for 72 hours and you can order it in any scent you want.
Happy Candles also offers full gel candle making instructions if you would like to try your own gel creations. There is even a handy wick size chart at the end to ensure your candle burns properly.
