Construction of a Bowling Ball

The video tutorial explains the two main components of a bowling ball: the core and the coverstock. The core, which influences 20% to 40% of the ball's behavior, can be made from materials like bismuth graphite or ceramic, affecting the ball's impact. The coverstock, responsible for 60% to 80% of performance, is made from materials like reactive resin, enhancing friction and oil absorption. The video details how these components and their materials affect the ball's performance on the lane.
