It is pretty cool. The you turn the can upside down, pop off a cap, push the bottom in, wait a few seconds, turn the can over, and POOF!!! In just 8 minutes you get a 140 degree latte without an expresso machine.
The kicker is that it tastes pretty good too!! As you can see below, it's not all that bad for you either. Well, unless it somehow breaks open and covers you in whatever toxic waste it uses to heat the coffee.
Oh well, I guess the hot coffee is worth it :)
Try it out while it is still cool to do :0
