/diy/ - Do It Yourself

What are some unconventional things you can use a stovetop and/or oven for? I am moving into an apartment and the rental agreement has the gas usage included in the monthly. The elec isn't so I'm trying to figure out what I can use my stove for instead of the wall socket.

Things I already thought of: A pot of boiling water (or making soup) would work as a humidifier, and I can pan, bake or flame-toast instead of a toaster, but there's got to be other things that I can do without burning my unit down.

P.S: What is the best way to keep the stove top free from getting nasty after cooking? Tinfoil on the parts I'm not using?
