idea: electric can opener with a dull blade designed to wear out every month. people have to purchase a subscription for can opener blades. alternatively, special cans could be designed to only work with the can opener provided, and a can subscription must be purchased. the can opener connects to the internet and has its own app so that you can share on twitter or Facebook every time you open a can of beans. the product's name has to be "iOpener," because it'll be really eye-opening once you figure out just how much money you got scammed for.
