Some athletes warm up with equipment from other sports

Baseball superstar Shohei Ohtani uses a cricket bat; his teammate Yoshinobu Yamamoto throws a javelin. Quarterback CJ Stroud shoots free throws.

The world's longest-running science experiment aims to prove if pitch is a liquid

Having run continuously since 1927, the pitch drop experiment is designed to show that the seemingly solid derivative of tar is a liquid by watching to see it drip through a tunnel. From 1930 to 2025, the substance has only produced nine drops, such that its viscosity—resistance to flow—is about two million times more than honey.
