DIY Stove Made from a Paint Can, Toilet Paper, and Rubbing Alcohol Keeps You Warm in an Emergency
If you're worried about car trouble keeping you stranded overnight in freezing weather you can create an easy and nearly free heat source by adding a roll of toilet paper to a new quart paint can and pouring a bottle of rubbing alcohol over the TP.
Emergency preparedness weblog Prepared Not Scared also notes that you can place the quart-sized heater inside a new gallon paint can with holes punched in the gallon can so it can serve as a pot stand to cook on the smaller stove. This works well as you can fit the smaller stove, matches, and other accessories in the larger perforated gallon can and have a ready-to-go kit when needed. To use, just pour the alcohol over the TP, wait a few minutes for it to be absorbed, and then light the stove using a lighter or match. It will burn for a couple of hours and can provide life-saving heat in an emergency situation, but if using in an enclosed space make sure you have some ventilation to avoid carbon monoxide buildup. For a total project price of around five bucks, you may want to consider keeping one in your car trunk.
