Equipment

Required equipment is fairly simple and inexpensive: junior tennis racquets and standard lawn tennis ball. In decades past, modified tennis balls were manufactured for the game. They had higher pressure and were slightly smaller than tennis balls. The last specially manufactured ball was green, so that it could be more easily seen against white walls. Early courts had dark wood walls so that white tennis balls could be seen. Players now either use a marker to darken a yellow ball, or use coloured tennis balls (such as the pink ball sold on a limited basis by Penn to raise money for breast cancer research). Blue painter's tape can be used to add the additional lines on the floor and back wall of squash racquets courts.
