A cannon describes a bowl striking another bowl to change its final position. This collision allows a player to nudge a teammate closer to the jack. It can also be used to knock an opponent’s bowl away. The angle of the impact determines where both bowls will eventually stop rolling. Precise execution turns a mediocre shot into a high scoring point for the team. One player use a cannon to push a trailing bowl forward. This contact moves the scoring bowl into the primary target area. Players must judge the speed perfectly to avoid sending both bowls out. Practicing the cannon shot improves a bowler’s ability to recover from bad starts.
