Following the rodent-carcass beer from yesterday, here's another major step forward in the world of packaging: the Canwich, a sandwich in a can from Mark One Foods. Many believed sandwiches couldn't or shouldn't come in a can, but this proves them wrong. Mark Kirkland has been working on the Candwich for more than a decade and has hit many snags along the way. But in August, the PB&J Candwich and BBQ Chicken Candwich will finally come to market. They stay fresh for a year without being refrigerated, so you know they must be good. "It's been a long, hard road," says Kirkland. "If I didn't really believe in the product and I didn't have a good wife, I'd probably be dead now." His challenge for the next 10 years: a sandwich inside a can inside a chipmunk.
