Instant-hot Latte

These things have been around for a while, but this one appears to make a mean cup of coffee in about 7 minutes. Basically, it's a can full of quicklime that you shake which, though the magic of chemicals, heats up to a scalding temperature.

The makers expect that soon everyone will be eating and drinking out of self-heating cans until someone spills hot soup on their lap or gets scalded by exploding quicklime and then they'll ruin the fun for everyone else.
