A jazz musician named Teri Pall invented a version of the cordless phone in 1965 but could not market her invention, as its 2-mile (3.2 km) range caused its radio signals to interfere with aircraft communications. In 1968, she sold her rights to the cordless phone to a manufacturer who modified it for practical use.
A hat trick originally meant three goals in a row, with no intervening goals by either team. Hockey borrowed the term from Cricket. In 1858, a cricket player in England took three wickets with consecutive balls, an incredible trick. As a reward, his club gave the bowler a new hat, hence the term “hat trick.”
