New Spray Paint Cans That Stop Spraying After The First Squirt?

I like tossing the cans into the burn barrel, sort makes boom like the guys that ignite black powder under 200 lb anvils!

in 6th grade there was a kid that did that. He was in the hospital for several days with massive facial lacerations. As soon as he tossed it into the burn barrel it exploded and shot metal pieces at him. I remember him telling me about it. I used to throw them in the burn barrel too... but not since then.
