Today i made a small pot using an old tuna can. I put a handle on it that was made of a clothes hanger, wrapped in insulated wire. The wire makes it so the handle is cool to the touch when boiling water. The only problem is the first time you use it, the plastic on the inside of the can blackens and peels off. Other than that, it works fine. Also remember to take off the paper on the outside of the tuna can.
