Hi Roger, When I was running an educational electronics lab I
discovered that student proofing was hard. I did have one technique
that worked fairly well though. I posted warning signs liberally
around the lab threatening re-arranged kneecaps for violators and
showing a pictures of my own cartooned self holding a baseball bat
and looking surly. Then in my office I kept a Little League sized
aluminum bat on the wall. Every now and again, when I had to remind
students about destroying lab equipment, I jovially carried around
my little bat. I smiled a lot and joked some and, amazingly, lab
tools started lasting quite a bit longer. Maybe some adaptation of
this process might work? Threaten tong assisted nose jobs perhaps?
Or maybe tin-snip assisted earlobe trimming? Torch style tongue
piercing? Be creative.
