If you would like a good small space heater, you can make one yourself with a coffee can, a roll of TP, and a bottle of rubbing alcohol. Be careful because the coffee can will get hot. You can use 2 cans putting one inside the other with sand underneath and around the sides to help with this problem. The TP acts as a wick and usually you will go through 2 or 3 bottles of alcohol before it burns completely up. The alcohol also burns with no visible flame and is oderless.
ONCE AGAIN.......BE CAREFUL.
