Got Balls?: Literature Review
Anyone who has ever gone bowling must be familiar with the brightly colored balls used to knock down the pins. But few people have ever really paid attention to the science behind bowling and realized how much of an influence aspects of technology has had on the advancement of this intriguing sport. Some people think of bowling balls as “just a ball” but for others, bowling is a “serious sport” (Falcioni). To the serious bowlers, it is much more than “just a ball”. There are hundreds of different types of bowling balls that have been created, each made a little differently. Bowling balls have different types of what is called cover stock, which is just another way of saying the outer shell of the bowling ball (Falcioni). One of the new, most popular types of cover stock is called reactive resin (Falcioni). Balls with a reactive resin cover stock give bowlers a better chance of striking because the angle into the pocket is greater as well as the amount of energy transfer (Falcioni). Reactive resin was mixed with a substance called urethane, which in the 1980s was found to be more effective on the lanes than polyester shells because tiny pores in the shell increased the friction between the ball and the lanes (Falcioni). Each outer shell of a bowling ball has tiny pores, just like a person’s skin, that soak up the oil on the lane. The development of reactive resin shells enhanced this sport because the pores on this shell were tinier than other shells, meaning it would take longer to soak up the oil and thus would have a greater hook for a longer period of time. Once a ball soaks up a significant amount of oil (if the ball is not cleaned with a towel frequently by the bowler), it will simply slide down the lane and decrease its amount of hook (Carton). New developments in the cover stock of bowling balls have prolonged the amount of time before a ball simply slides...
