LASER CLEANER: removes rust, old paint, etc.

Reminds me of one of our former senior researchers, now 'retired' but still active, he told the story of beam path idiocy involving people moving mirrors and stuff live in a multi-megawatt facility, he cured most of them by hanging half a pig in the beam path and blowing large holes through it with each beam 'shot'...

I have a screwdriver that I used to test a laser I was adjusting, has a hole blown halfway through the large plastic handle. Good conversation item for people new to lasers.
