You're right Pistone, residues can be extremely dangerous. A kid was killed in a shop class explosion up here. He was cutting into a drum that had peppermint oil residue in it. I believe charges have been laid against the school, the teacher and the board. Won't bring the kid back though. It always amazes me how stupid people can be. I find it hard to believe a shop teacher couldn't be aware of the dangers involved in this type of activity.
