[step] If you have any candles you don't want, these are an ideal source of wax (like the stub of a candle). [title] Melt the wax in the can.

Ending1: [step] You could put it on the stove in a pan of hot water, or put it in a slow cooker. Do not just warm the can straight on the top of the stove since that presents a serious fire risk from over-heated wax. Ending2: [step] To do this, use a lighter and stir continuously in an electric can for 30 seconds. It will only take about two to three minutes for it to melt completely. Ending3: [step] Liquid wax is not recommended unless you have a fire surface to work on, but any plastic or gas can works just fine. Place a small amount of wax in the can and let it melt slowly, stirring constantly. Ending4: [step] This will (possibly) indicate that you are burning something and that you will need to add a little wax, by using several drops in the can to thin out the wax. [title] Pour the wax evenly over the candle wick.
