Coffee can
by Dave Harden
(United States)
Toilet paper is a small one that is overlooked. How about this one for supplemental heat. Coffee can, Roll of toilet paper and rubbing alcohol, lighter.
The toilet paper acts as a wick and absorbs the excess alcohol, the alcohol burns clean. You can use the can to hold the contents. The can lid can pur out the flames.
I learned this from the Colorado Division of Wildlife.
