The Greatest Candle-making Powder In The World is genius. You can either use up old cooking oil, or use new cooking oil to create a super-cute candle in a matter of minutes. All you have to do is stir in the powder to the strained (if you are using old cooking oil,) oil, and microwave on high for 2 minutes. You then add a couple more tbsp of the powder, mix again, and pour into a container of your choice. What I love so much about this craft is that you get you make candles in all those adorable little pots, tins, shells, and glasses that you stashed away thinking they might come in handy one day. It’s a brilliant craft for kids because no flame required.
