Tom,
Although I found this quite funny, I am still trying to figure out what
purpose this exercise serves. I have never been really deep on air (~150
ft), and quite frankly I have absolutely no desire to find out what that
is like, not even for two breaths. If there were no trimix I still would
not go that deep. This to me is the equivalent of trying anything that is
commonly known (deep air is by now) as being stupid or dangerous, just to
have tried it! Call me naive, but doing something like this once and then
never again (after completed trimix course) just doesn't fly with me. I
will quite happily accept just being told that my head will spin really
good at that depth (or whatever it is that happens down there) and
anything I were to attempt would be impossible to complete in a reasonable
manner. I don't have to try it out myself because it will never happen
again. EVER. Is it just the sensation of deep air you are demonstrating
to the students, or am I missing some other point here? It sounds almost
like closing the shop door and breathe gas fumes for a while until your
brain hurts, and then go outside and be really happy when the head ache
goes away again. Wouldn't make me any smarter, I'll tell you. I already
know the answer to what not to do there.
