Make Your Own Stove/Emergency Heater

Here is a great link to making your own alcohol stove in a paint can. In an old ward for RS we made these in our super saturday! They were great. These can also be used to heat a small room. I think at the time I had made 12 (one for every room in the house plus a couple).
