Propane Tank-ard

[hpstoutharrow's] new instructable is a neat idea on how to re-use those single use small propane bottles by turning it into an insulated canteen. Once the bottles are emptied through normal use, the safety valve is popped loose and allowed to vent. There are also comments on the article that suggest that the bottle be submerged to ensure all gas is gone, and we think that is wise too.

Once safe to work on, the bottom is cut open and the stem is cut off leaving a empty shell, a soda bottle is shrunk down by boiling water inside of it for a little bit, then is fit inside the propane bottle. The top of the soda bottle is held in place by an O-ring, the safety pressure hole plugged up and the whole thing is filled with spray “expand-o-foam” locking everything in place and adding insulation.

Though using a thermoplastic bottle as its liner does not invite hot beverages to the party, it seems to do the job just fine for cold drinks, and it makes for a interesting conversation piece out on the campground.
