I don't see any instructions for bleeding the pressure off these cans. Are you certain that depressing the spray can nozzle button will exhaust all the pressure? I have always heard that cutting into pressurized cans can be dangerous.

I think the impression that they're explosively dangerous is slightly overblown. If you spray the nozzle until the can is empty and then put the can inside something to protect yourself from any shrapnel, and then puncture the can with a nail, you should be fine. A guy on Flickr wanted to see what would happen if he punctured a can. He built a wooden box just bigger than the can, with a hole at the bottom-side for a nail. He punctured it and there wasn't much pressure release. I think if you guard against anything being able to flying at you, wear goggles, make sure the can is as empty as possible, etc., you should be fine.

I love this idea. I have a concern about removing the bottoms from the cans, even after depressurization. Any advice or experience?
