[pct-l] Canister Stove: disposal of empty canister.

[david booth]

I have been using these stoves for many years but always worry about  
sensible disposal.
I dumped an 80% empty canister in a dumpster bin at a campground once  
and had visions of a small explosion sometime later as the canister  
was crushed and ignited by a spark.
Snow Peak sell a small punch but it is heavy and costs $9.
I now use a small carpet nail that can be successfully hit with a  
rock to put a hole in the canister.
Then a foul-smelling greenhouse gas emerges to ruin the atmosphere of  
the planet.
The other option of burning all the remaining gas can take a long  
time and also ruins the atmosphere by pumping out CO2.
