I'm thinking of getting some of those really small aluminum drink cans, I think they are just under 8oz of fluid content. Cut the inside top off, make a cozy, and have a very small cup for hot drinks. This would fit inside my Caldera Cone that is rolled up inside a cut down 1L plastic bottle.
I could make tea in it easily, but I'd like to make hot chocolate. Question: would stirring the hot chocolate scrap off the thin plastic coating that is on the inside of the can? How fragile is this plastic coating?
Thanks for your thoughts.
