Bert Hickman, a retired electrical engineer, frequently reduces his pocket change without spending it. How? He puts a single coin inside a copper coil, then with the help of a 600-pound bank of 12,000-volt capacitors he shrinks the coin to nearly half its size.
Hickman isn’t left in the lurch though. He sells the electromagically shrunken coins for $10 to $20 each. You can find out more about the process and how to buy them at his web site, teslamania.com.
