In this tutorial, we learn how to start a cozy fire with lava rocks soaked in oil. First, grab your lava rocks and place them in a tin can, then fill it up with oil. Now, throw some wood into your fireplace while these are soaking. Use an old pair of metal tongs to take the rocks out of the can, then place them in the fireplace as well. After this, throw a match in with the rocks and wood and then close the fireplace. Let the rocks burn for about 5 minutes the you can take them out and you will have a nice fire for the night!
