Hi Jerry,

Yes, in writing my book we included safety guidelines for general demo
use, and these could be looked at and adapted as a general warning if
that would be appropriate.

I am also a bit leery of a "danger" ranking, as that could lead to what
you suggest. It also begs the comparison of the "Beware of Dog"
sign....people who hang the sing on their house are more liable to
getting sued if their dog bites someone, as it is an acknowledgment that
they know their dog is dangerous (!)....the same reasoning could be used
for "dangerous" demos, and it may be a way to increase liability if
something does happen when using one of them in class.
