I personally use way more of the dollar general fruit punch gallon containers than milk gallons, and Like Inor said, I have added some to my chest freezer. In Arkansas, we kept one in the freezer to add to our fish cooler.
Could you possibly list the ingredients here, I am a pyro at heart. And it would make a great target..They make good targets.
In all seriousness I do not know the concoction but my brother inserts a glass tube into a milk jug filled with other chemicals and went it is hit with a bullet it creates quite a fire, not an explosion but a pretty nasty blaze. That can be useful in certain circumstances.
