Turn a shot glass in to a lovely tea light candle.
I seem to have a huge shot glass collection and I can't remember where many of them came from. I was feeling somewhat obliged to keep them so instead of piling them up in a cupboard, I turned them in to tea light candles.<br><br>
You could really use any kind of glass for this. Experiment with pretty glasses like martini and cocktail glasses. Don't use plastic shot glasses though or they may melt away.
