Make a candle last longer by freezing or salting it
What happened: Those fancy candles in Southern Cotton or Angel Food Cake scents seem to melt to a puddle of wax in the time it takes to relight a match.
What to do: Credit Bob Vila for these two odd tips that actually work:
Store your candle in the freezer overnight. Then, take it out right before you burn it. After you light your candle, let it melt a small puddle of wax around the wick. Then, blow it out and sprinkle table salt into the liquid wax.
Both techniques slow down the rate at which the wax melts. They can be used together, too, for better results.
