Social networking is changing our lives in a variety of ways, and now it's entirely revolutionized how you get hot soup into a sick friend's belly. Heinz has launched a U.K.-only Facebook app that lets users send real cans of Cream of Chicken or Cream of Tomato to a friend for about $3 per can. The package features a "Get Well Soon" message and your ailing friend's name, but as it still relies on a series of humans to convey the can to your friend's doorstep, the process could take three or four days. Heinz, please alert us when you've invented a Star Trek-style replicator that can instantly put this vital medical treatment into our loved one's hands.
