coffee stories

If you're in the market for a new death ray, an important thing to consider is what you'll be able to do with it when you're not busy committing nefarious acts. One option is coffee roasting, and, if you're so inclined, you can even contribute to an open source project that's looking to create a giant mirror array capable of superheating air to 2,000 degrees.
The window of enjoyability for hot beverages is pretty small: you've got about 30 seconds of 'just right' between tongue meltingly hot and disappointingly lukewarm. Giant magic beans with liquid metal inside use the power of physics to simultaneously make hot things cooler and cool things hotter, prolonging that ideal temperature.
With clever designs like this one, the personal coffee-cup insulator could be poised to become the next big gift item. Conceived by a teacher in Ottawa, Ontario, the "Caffeinating" coffee cosy is perfect for hard-core tech and coffee geeks alike.
