Homemade foot warmer keeps feet warm during power outages

Ukrainians can create a simple homemade foot warmer using a sock and rice to stay warm during power outages. The method involves filling a sock about a quarter full with rice, tying it off, and then heating it in a microwave for one minute or on a stovetop over low heat. This reusable warmer retains heat for 20-30 minutes and can be reheated. Other grains like buckwheat or flaxseed can also be used.
