Abstract
A game ball is provided for primarily practicing throwing a football in a passing spiral motion to impact a vertical wall, and then via a reactive force, the game ball returns in a passing opposite spiral motion to be caught by the person, who is practicing throwing a football. The body of the game ball has an external appearance looking somewhat like a football, except having only one conical pointed end, referred to as the trailing end, and having the other end, referred to as the leading end, being a substantially planar wall contacting surface. The body is made to absorb a substantial portion of the wall impact energy, and to quickly release a substantial amount of this absorbed energy, which is then directed in the opposite direction, successfully causing the body, serving as the game ball, to return in a passing opposite spiral motion to the locale, where the game ball was initially thrown by a person in a passing spiral motion.
