I have a background in programming, but a program by itself has limited use. I was like, man, I need to make a project that will actually control something. I had my old mini-fridge from college lying around and, I thought, how about an iPhone-controlled drink vending machine? So I did it . . . and it sucked. You could control it from your living room—or from China—but the cans just rolled out onto the floor. It was a pain to walk over and get them. I wanted to get a beer to travel from the fridge across a room with minimal effort and maximum cool.
Go here to see how you can build a beer cannon just like Ryan's.
Never a part of the world to let common sense stand in the way of a good vending machine, China has now invented a machine that, for the equivalent of a couple of dollars, pops out a live crab. The Shanghai hairy crabs, prized for their roe and sweet meat, are stored in the crab-o-mat at a near-freezing temperature, which keeps them alive but in a motionless state of hibernation. If your crab is dead when it comes out of the machine, you get three more crabs for free, guaranteed!
