I use my two Burmese in school presentations almost weekly. Since July 2002, I've done 199 of these presentations -- mostly to schools, but to some civic clubs, etc. I have used three different snakes for these presentations, all Burmese. Sadly, the star attraction, my 16 1/2 foot albino female, died in October 2003. I now have two males, one 14 feet and the other about a foot shorter, that I use. After I do my presentation, I usually let the kids touch the snake if possible. I've spent the entire day at schools and had as many as 800 kids come up over the course of the day and touch the snake. So far, I have had no incidents. I realize the possibility of a bit or strike is definitely there, and I go to great lengths to make sure the kids are safe. The good thing about using a big snake is that you can stretch the snake out on the floor and the kids can touch the animal without getting near the head. Another key is crowd control. I make sure the kids come by in a single file line and gently pet the snake and then move on. I keep them away from the head, and I try to keep my hand or arm between the snake's head and the kids.
I have taken a couple of hits myself doing shows, but none recently. About a decade ago, I took a nasty bite on my forearm from a big African rock python in front of 120 Boy Scouts. But the kids were well away from the snake. For the record, none of the bites I've received during shows have been from Burmese.
The key is to be very careful. If one my snakes ever bites anybody (besides me) during a show, my days of doing the shows will be over. So I go to great lengths to make sure that doesn't happen.
