Hamada’s Got You in Hot Water

When you’ve got disaster, you need heat. The Onsui (hot water) works for disaster area victims by generating heat without fire. Pour your water in the Onsui, wait a bit, pour the hot water out. Make some food, eat some beans, some crackers, and fix that disaster up.

Each Onsui has a heat cartridge that makes the water hot once it’s in the container. Water can be boiled in the container by “the hydration of water and quicklime (calcium oxide.)”

And, of course, it’s a nice jug too.
