I had one explode in the shop - no idea why but it sprayed foam 5hit across 20 feet of shop floor.I had just moved too, so it landed on all that crap that hadn't been put away yet
Don't put those cans of foam on your dash board with the defroster going either. My grandfather found that out the hard way in 60 MPH traffic on I-5 He said it was one heck of a ride for about 10 seconds
It's amazing how much work a guy can create from being a little bored. I'm glad you're able to laugh at yourself. I usually go into "burn the house down" mode.
