Hi Stephen,

Funny you should mention this, and it's also interesting that one of our
first (major) accidents is in using H and H/O balloons, something I
never thought of as an area of concern. Certain inherent danger, of
course, but I had never heard of trouble with these till now. The
discussion about these and the cause of the spark/explosion has
certainly been interesting.

I was actually hoping we could make an effort and produce some
guidelines for laser pointer safety. They seem to getting more powerful
each day and it's gong to take only one case of laser pointer blindness
to keep them out of the classrooms. And I'd hate to lose them as a
teaching tool, as they are great in many experiments & demos when used

A rating system perhaps? I'm a little ambivalent because I believe the best protection is a good understanding of what you're doing. But even the best of us can make mistakes or be lulled into a sense of security because nothing has ever happened doing things the same old way.
