Interesting article in the December-January issue of Field & Stream magazine. Basically survival tips should you be stranded in your vehicle in a sudden snow storm. Apparently this very thing happened last hunting season out west and several hunters were trapped for a week. One interesting item he gave instruction on was making a toilet paper heater. All you need is a standard sized coffee can, roll of toilet paper, and rubbing alcohol. Scrunch up the TP and remove the cardboard center. Place it in the coffee can and add 16 oz. rubbing alcohol. Let the alcohol soak in, then light. It DOES produce carbon monoxide in small quantities, so window ventilation is a must. When no longer needed, just blow it out, wait for the top to cool and put the plastic lid on and it's ready for re-use. The author claims up eighteen hours of intermittent burning by adding more alcohol. When the TP edges start turning brown, you need more alcohol. He states that he kept a topper like camper warm in this manner. He also said you can actually still use the TP after the alcohol burns away??????
