One I thought of on the fly which worked quite well - the site I work at has a rock just outside the safe area with a nice "socket shape" hole in it. Put a swollen picked up ball in the hole, shoot it - instant respect for goggles.
As for the safety talk, when I do one I spend probably 3 or 4 mins at the start, then re-inforce it again at the end of the talk - after all the info about how to get shot, how the marker works, how to do this that and the other, the punters tend to feel information overload, so it's worth reminding them to not get blind.
(and for the real muppets who still lift, there's the fact that a point blank shot to the eye at 300fps will actually take out a 3 inch cylinder of your brain - if the shock doesn't kill you, the blood loss will - how many paintball sites do you know which are right on the doorstep of the local hospital?)
