The idea of this activity was to teach all of the Scouts how to light a fire.
The method we tried and have a lot of success with is the lean-to method.
Basically start with a larger branch at an incline.
Next place you tinder (bark, paper etc) underneath the branch.
Then lean thin twigs against the branch (see picture below).
