Since last year Manu has been collecting wax from burned up candles on Diwali and has been repeatedly asking to make a candle out of it. We finally got around to doing that this year and realised it is surprisingly simple and doesn't make any mess that we thought it would. This particular candle was made in a glass. Mira melted the wax and poured in in this glass. Now the next thing to add was a wick and since we didn't have that, we placed the regular cylindrical candle in the melted was. When it froze, the candle was ready.
