This just reminded me of the time I put a vent in a battery.  I was about
14, and had heard something about rechargable batteries.  Well, I had a few
D cells (alkaline) sitting around, so I thought I would try it.  So, I tape
a couple of wires to the ends, and proceeded to plug it in.  ZAP - POP,
instant vent hole about .5mm in diameter.  Scared the _ _ _ _ out of me.
