What to do with empty co2

[jimmypop]

A great idea.. weigh them in and proceeds go to charity. But don't forget, empty CO2s make useful targets. As they still weigh the same after being shot to shit, they can still be sold for scrap afterwards.

I stick mine in the local church's can recycling bank, they weigh a bit so must be of more value than coke cans and they get the cash for it, thats my seat in heaven reserved!
