>>96082139If you have a microwave and rice you should fill a sock or sweater with the rice, make sure you tie it secure and then microwave for a few minutes until warm, dont burn it! this can keep you warm for a couple hours.
If you dont have a microwave you can just boil a bit of water and use a simple bottle to keep it from spilling. hold onto the bottle or place it under blankets ,watch for spills!
