a venus fly trap garden?

When my students were asked "what kinds of things would you like to grow if you had a garden?", some of the responses were as follows: carrots, corn, cabbage and turnips. Sure, these were the answers I was looking for BUT they were all a bit "safe", too. However, one student had to throw VENUS FLY TRAPS into the mix... likely just to see what my reaction would be? It is worth mentioning that this was the same boy who said that magma was a resource that we could not live on this earth without--enough said.
