|One Brand Of Beverages|
First I found self heating beverages, these are 7.1 ounce cup/cans. Let me explain. Wrapped in a nice foam label is a metal can with a pull tab on one end and a plastic housing on the other. The plastic end has a foil cover. The way it works is relatively simple. First you give the beverage a shake. Then flip it over so the plastic side is "up." next you pull off the foil and press down on the plastic "button" underneath. Flip the can back over and set it down on a handy horizontal surface. I gave it a couple of extra shakes to get things going. Probably doesn't need it... but who knows! Now wait about 8 Minutes. After that, pull open the can "pop-top" just like the ones on a can of soda. There you go, instant hot beverage! It's pretty cool, and surprises everyone who sees it.

How does this work? It's really simple chemistry. The plastic side of the housing contains water. Just above that is Calcium oxide also known as quicklime in solid form. When mixed, you get an exothermic reaction. That's just a fancy way of saying it heats up. There are other chemicals that can be used, but this seems to be the most common. Pretty cool use of basic science!
Speaking about meals. There are a couple of varieties of self heating meals on the market. In a later article I'll try a few and let you know the results! I may not be the best judge of flavor. After all, I like airline meals and MRE's! (Meals, Ready to Eat... courtesy of the US Military).
