Flora,

This is a hard one. And we all know that no matter WHAT we do, no matter
the precautions we take, people are going to get hurt. I mean, how many
times did you smash your thumb pounding in 2500 nails???? It's just a
fact of life. And, some demos are just inherently a little more risky
than others. I've reached in too close to the VDG and gotten zapped a
few too many times (which explains a lot, if you know me! hehehe).

The main problem is this: by putting IN safety regulations, you are
admitting you know certain demos have a degree of danger, which opens
the university up to liability. What you will have to decide, in EACH
demo's case is if the degree of danger outweighs the risk of liability.
You'd think that by installing safety regulations to go along with your
demos, you'd be HELPING, but its not necessarily the case when speaking
legaleze. But, if it were me and my department, I'd fight for the safety
and the lawyers be damned. If I had chipped someone's teeth
accidentally, I'd not want it to happen again.

If you decide you want shielding for the bed of nails, contruct a shield
by cutting a "bite" out of the center of one edge of a 2' x 2' piece of
plywood. Attach door pulls to the side that will face the person on the
bed for them to hold (this also puts their arms behind the shield).

As for other demos, I'd hired someone like Karl Trappe as a consultant
(he's on this list) about safety of the demos you have and things to do
to make them safe(r). He's got decades of experience doing this stuff.

Ok Folks...

The bad news:
There are NO Sutton CDs left. I will not be burning more to sell
throughout the year. I just don't have the time and energy to take on
being the PIRA store.

The good news:
AAPT will have the reprinted book available in their online catalog
soon. How soon, I don't know...AAPT is recovering from the meeting and
gearing up for major publications right now, so they're busy, busy,
busy! I will post more when I know more. They've been a fantastic help
and I know Sina works hard to get these things done for us.

We (PIRA) have been given rights to post the CD on the web at the PIRA
site and I will be doing this as soon as I can. There's some logistics
to work out first. I'll make an annoucement about this when it is done.

You have been given waaaaaay to little information!

Is this person interested in physics? Or interested in avoiding a
ticket? If the later, you should get paid for solving the problem (with
more info...).

In grad school I earned $100 solving a simple physics problem for a
lawyer whose client had been stopped for speeding. He was hoping that I
would show that it was impossible for his his client to have been going
as fast as the ticket said. Alas, I was only able to prove that his
clients pickup truck was more than capable of reaching the stated speed
in the stated distance.
