I'm sure many know how to do this but for them that don't here are two SHTF candle's I just made, the small one has been burning a good hour now and the large one around 40 mins.
You will need jar or tin, I used cotton wool wrapped around barb q sticks, cocktail stick would work, I used sunflower oil, any cooking oil should work, I'm going to try some real cheap oil whe i get chance to pick some up.
