Also, I live with parents who don't know of me smoking, and I'd like to keep it that way. My plan is to do this experiment in my basement bathroom at 10 or 11 at night. I'd really rather not stare at a crock pot until 3 or 4 in the morning, so I was wondering if I could do this in my room. I was thinking about putting it under my desk on my carpet, but I'm not sure how safe this is, and how hot it'll get. Any advice?
