Uncover the microscopic shockwaves that cause everyday materials to shatter. When a brittle object snaps, the initial fracture sends a powerful ripple through the remaining pieces. This hidden wave forces secondary breaks before the object can even straighten out. Understanding this snap-back effect reveals the surprising mechanics behind structural failures in our daily lives.
