Common office toy inspires new weapon -- the "Sound Bullet"
A toy commonly seen on office desks has inspired a powerful new weapon that could be used to destroy everything from tumors to submarines. Researchers at the California Institute of Technology modified Newton's Cradle, that series of stainless steel balls suspended by fishing wire, to create extremely focused and destructive sound waves. See how they did it in this episode of "Innovation Nation" with Miles O'Brien.
