Inspiration comes from the strangest places. A falling apple supposedly inspired Newton’s laws, and now a desktop ornament bearing Newton’s name has inspired a new acoustic weapon that both militaries and hospitals can keep in their arsenals: sub-sinking, tumor killing “sound bullets.”

Researchers at Cal Tech, using a modified renditions of Newton’s cradle – those stainless steel balls suspended by wire that make a seemingly endless clatter once set in motion – have figure out a means of concentrating and amplifying sound waves in a way that makes them an extremely destructive acoustic force.
