Beer cannon

A US man's invention of an iPhone-controlled fridge which can be programmed to fire cans of beer across a room from a cannon will ensure people no longer have to walk to the fridge to get a beer.

Ryan Rusnak, 25, created the 'Beer Bot' by adding a compressed air cannon to a basic vending machine that dropped chilled beers from the fridge into a tray below.

He said: "It was kind of famous last words: 'how much pressure should we use?' The first attempt smashed the can into the roof and blew it into a thousand pieces.

"All the tinkering and everything took about three months to get it absolutely right.

"After working an eight-hour day, coming in and firing a can to yourself is just the best thing. Even now I've fired it hundreds of times and it's still cool."
