Self-heating cans are WKTE (ooh, so hard not to say "baked"
there). Fine for liquids but not so much for thicker
doesn't conduct as well through viscous contents.
The solution could be a spring-wound agitator build into the
of the can, to shake or stir contents
while heating. If it
a ticking noise while running, it could also server as a
timer, and perhaps trigger a security over reaction if used in

||I miss read this as Self Hating Can With Alligator!
||If you can train the alligator to shake it, why not?
||Why not indeed ? Please demonstrate your trained alligator, and make it snappy ...
||Oooh, I know how this could be done. Inside the food/drink
compartment, you have a magnetic stir-bar, really just a
plastic-coated magnet with a blob in the middle so it spins
easily. In the heating compartment you have the magnetic
driver, really just another magnet that couples through the
divider to the stir-bar. The magnetic driver spins because
it's attached to a wound-up clock spring. The clock spring is
potted in wax before heating so it doesn't move. Once you
activate the heater, the wax melts and the stirrer stirs.
||I like the idea of a pre-wound spring activated by heat.
|| My original idea was just to have the spring spin an
unbalanced cam/weight, to make the whole thing shake
while cooking. But I don't know how fast it would have to spin
to get a good shake, so a stirring rod and something to
regulate the unwinding might still be needed. And the
escapement could make a worrisome tick-tick-tick noise
while it's running.
||Perfect for picket lines in winter. [+]
