I had extra cooking oil that was used to fry tortillas for enchiladas. I couldn't just let it go to waste, so I made this support for holding a cotton wick. This can be used to make any oil holder into a nice candle. If you are careful with the oil level, the wick will be consumed very slowly.
**rancid olive oil burns more efficiently, so dont throw it out* Make Your Own Olive Oil Candles. Olive oil burns clean and doesnt smoke. You can make these lanterns in any size of jar that you have on hand. Also, if you want them to be scented, you could add essential oils (or even dried or fresh herbs!) right to the oil.

Cat Food Can Candles - inexpensive emergency prep project. Use any size can or jar. Can use old shoestrings for wicks and break big pillar candles from thrift stores into pieces for melting. Add soy wax flakes to add hours to the burn time.
