Deconstructing the Puck self heating coffee can
Related entries in Coffee Experiences, Coffee Opinion, Coffee newsSo, a while ago I wrote about Puck’s self-heating coffee, and now they’ve been deconstructed on Make.
Inside the mug is the self heating element. And, inside that, 8 oz of minerals. White powder with little rocks. Lovely.
So there it is, an exothermic reaction (gives heat off) with water and calcium oxide. You can easily remove the liquid and use it for something else. I’m not sure what- but i think there are some uses for this. It’s constructed like a tank, so I bet military and outdoors people might be using these.
One of the best uses might be to remove all the materials (before they’re heated/water added) and show how chemical reactions can be used for something tangible for students. You could also likely do some neat things with the materials for experiments that require a small amount of heat.
Educational, yes. Drinkable, no.
