I have done it with a scout group -once, the kids loved it;
but I agree with John it was poor judgement by me.
The Moon may be boring with us, but kids are really wowed,
much more in my experience than those "little things" up there.
Yes, there is always the possibility of "ow, my eye", even if it didn't happen. People are really out to get others these days. I won't do public outreach at all.
