Hammer throw The hammer throw is one of the four throwing events in regular track and field competitions, along with the discus throw, shot put and javelin. The "hammer" used in this sport is not like any of the tools also called by that name. It consists of a metal ball attached by a steel wire to a grip. The size of the ball varies between men's and women's competitions (see Competition section below for details).
Patball Patball is a non-contact competitive ball game played in many forms using one's hands or head to hit the ball against a wall – the objective being to get the succeeding player out. The game is popular in school playgrounds during break-time. Patball is played with a tennis ball, or other similar-sized specific patball, and the preferred hand, rather than any form of racquet or bat. The hand is used to "pat" the ball at the wall with the objective of making the ball un-returnable, similar to squash. In some variations of the game the use of the foot is also allowed.
