Preparing your kids to grow up to be a vagrant, transient or hobo? Give'm this RC metal detector, which lets them search for coins, watches, and other lost valuables wherever there's sand or dirt.
The cars run on 4AA and 1PP3 battery—9V to us non-Brits—and comes with a little plastic shovel and rake. Teach a man to fish, and he'll eat for a lifetime. Give a kid a metal detector and he'll go live under Santa Monica pier.
