Chop the candles to pieces.
Get a plastic bottle and cut it in half.Make it bigger than you will need.
I used a simple cheap white candle,that I melted and sticked to the bottom of the bottle.But if you have fuse at home,you get the same results.
Boil some water,and put a smaller pot in the other one.
melt the candle pieces.
pour it in the plastic bottle.
keep doing the same until your out of candle.
Now just wait until its dry and carefully cut the plastic bottle off.
And your done!
