Class pet help?

[Lolo76]

I work at a high school (as a librarian), and was talking to my boss yesterday about getting a "class snake" - and possibly turning that into a whole program on reptiles. She's checking with administration on the rules, but hopefully we can do this! I have a few questions, and was hoping you all could help...

1. What kind of snake would you recommend? Fyi, all boas & pythons are illegal within San Francisco city limits (where I work), although I may be able to get a permit for educational purposes. But I was thinking a corn snake, or something of similar size and temperament, would be the best for this purpose. Would LOVE to have a BP in the library, just have to find out the legality of that.

2. How should I house the snake? I use tubs with my collection, but don't think that would be viewer-friendly enough. It's pretty cool and wet here in the Pacific NW, though I should be able to maintain things in a glass tank with UTH... but I can't afford to purchase anything fancy (if I end up providing everything), so cheap is good.

3. Has anyone here done something like this, and if so, could you offer any more tips? For example, what's the best way to make this an educational program? And should I have them assist with everything, including the feedings? TIA!
