How to start a fire in a fire bowl?
you get paper and role it up in to balls and place at thebottom then put fire lighters and then put sticks on top then throw some coal on and light from under the paper.
Or, if you don't want to use things that you don't need to, the easiest way to do it is to build a little structure. Get some small twigs and sticks and such, and build a little square structure like the way you would with Lincoln Logs-alternating levels of parallel sticks. Then, you need something to ignite the sticks. Paper will work, but so will dry leaves. Unless you want to get your spark from flint, a lighter will work fine. The leaves or paper will burn hot and quickly, setting fire to the sticks. From there, you want to add progressively larger pieces of wood, trying to keep the original structure you started with.
