Looks like a regular vacuum flask. However, there is no insulation; instead, the base of the flask is made of refractory ceramic, holding a small but useful quantity of thermite.

A friction igniter triggers the thermite reaction, and the heat rises into the drink container, rapidly raising its temperature to boiling point or beyond.

The unit is-re-useable; just clip on a new thermite pack.

Guaranteed to break the ice at parties.

May cause death or serious injury if used correctly.

This would work well for those heartwarming mercury-based drinks. For anything else, I suspect the internal conduction rates would be woefully underinadequate.
