>>I was allergic to yolk, mustard and gunpowder smoke. Nothing big, I'd get a bit of a rash in a couple of places, or my palms would itch and redden. It would go away in a day. The gunpowder was funny to find out - we had those little toy guns with a paper tape and a bit of gunpowder between the layers of paper, and the hammer would hit it and ignite it, with a nice bang and a bit of smoke. Seems to be I got a particle in the corner of my eye, and that's how we found out.

>Yeah, caps. We used to hammer those things on a rock. Heaven only knows why; it wasn't all that exciting.
Well the cheapo toy guns would occasionally miss and move to the next dot, while with a stone you can always try again :)
