Since that 'boat plug' would outweigh the bottle that's not a idea I will go with. I have a cork in it now.

Mugs, Making a stove from it seems logical, but only if it can't be used as a vessel to carry something. Since it is a bottle made from metal I wonder if it is lined with anything? Does anyone know positively if this bottle has a sealer on the inside?

Reason I ask, is if I wanted to boil water in I would'nt want sealer peeling off into the water. It's a convient shape to carry, and use in camp. Must be 12 oz at least. I keep thinking Kelly kettle for some reason, but this is too small for that. I could set it inside of another pot that is boiling water for something else to make; then just pull the bottle of hot water out to use for tea or whatever?
