I'll teach you how to make candles for free. First, cut ash and colored crayons into small pieces, put them in a jar and melt them in water. Oh, by the way, don't forget to put the wick. Put the wax in a beautiful container, let it cool, and then paint it with a layer of color. Ok, put this candle in the water and light it. It's beautiful. This is called "wax bleaching". If you don't put it in water, it's called a candle. It's good. Why do you have to spend money? Save it. Supplement: Guilin Road specially gave Heishui Road and asked: Is this too difficult?
