However, if one of the bands Il against a rebound surface, as a side walk or the or I2 also strikes the rebound surface, the angle 5 like, will introduce an element. of uncertainty in of rebound will be aected thereby and uncerthe direction or angle of the rebound. tainty in the direction of return of the ball is Children play numerous games with rubber thereby introduced.
