Good on you, for allowing kids to learn about them. To me, there's nothing better. There's so much of a stigma, that everyone is so afraid of snakes, for really no reason.
Now, keep in mind, before we got Brutus (18' and 214lb), Harley was our biggest snake...and she's pushing 12' - 14', but only about 40lb. I've taken her and our larger albino Burm to my moms day care. Let the kids touch them, hold them and taught them about snakes.
It's just one of those things. Before I got into snakes, I was passionate about two things...I mean, rediculously passionate...that was flying (single and twin engine pilot) and saltwater fish. Now that I've gotten into big snakes, I'll have them the rest of my life. I'm not getting into this to breed and make alot of money...I'm doing it because I enjoy it and it's a passion.
I'll tell you guys what, though...
I handled my female Cobra, for the first time, last night. The male and female were supposed to be shipped in two different containers and they were not. Until last night, they were housed together and fought like cats and dogs (thankfully, when they bite each other, they're immune to the venom). I couldn't keep them together, because they'd fight over food, etc.
I've handled venomous before, but never owned any and never handled in my own home, with other people to worry about. I had Heather standing behind me, to back me up, while I transfered her to her new cage. I handled with a snake tong and snake hook and she got away from me twice. I dropped her and she was no more than 2' from my leg. Luckily, she's calmed down and doesn't hiss or strike anymore. Heather was right with me, telling me to keep it calm, etc.
I got her into her cage, put the hooks down and was shaking like I was a crack addict, having withdrawls.
