Soda Can Stove with 190 proof Everclear grain alcohol. Thats a barter item. I used to use denatured but then decided it had too much chemical so I tried Everclear and it works just as good. Plus its drinkable …. if you can stomach it. Ugh, but its ok diluted with coke or orange juice. At such a high concentration its lethal to most lifeforms including you if you’re no careful.
