Stone skipping is a recreational activity where a flat stone is thrown across the surface of a body of water, causing it to bounce multiple times before sinking. The goal is to achieve the maximum number of skips, which depends on the stone's shape, weight, and the angle at which it is thrown. The technique involves a flicking motion of the wrist and a low trajectory to minimize water resistance. Ideal stones are typically smooth and round, often found along riverbanks or lakeshores. Stone skipping is enjoyed by people of all ages and can be a fun challenge among friends.
