Their standard weight is 3lb. 6oz. but there are also pins that are now allowed (beginning in 1998) that weighs 3lb. and 10oz. Bowling pins are made by gluing blocks of hard maple wood together. Makers of bowling pins use these blocks to create the pin shape by using a lathe. The formed shape will then be coated with hard layers of plastic material and are painted white to produce a finished product that is shiny and pleasing to the eye. In the America alone, there are more than 7,000 bowling associations in different states that support countrywide competitions for more than 4 million bowlers. Americans find the bowling attitude the same as their culture, however, they are unable to take credit for the discovery of the game. Since bowling history is colorful and full of twists and turns, researchers have discovered that the game is actually the very first sport that was discovered. Bowling is a game that many people take very seriously. Keep common courtesy and politeness in the front of your mind. Don'ts Interrupt bowlers. It is considered a serious breach of bowling lane etiquette to talk to bowlers when they are trying to make a shot. Let the person who has the lane concentrate. When a strike is scored, no marking or counts are made in the boxes. However, the pins that were knocked down on the first delivery are scored in the box next to the small square. The pins knocked down on the second delivery are listed on the smaller box inside the square. A strike occurs when all 10 pins are knocked down on the first delivery. The fingers should be always be relaxed when delivering (swinging) the ball. 2. It is also recommended that a bowler learn the different styles and techniques of bowling. This will help him get used to the movements and find out which styles are effective for him in hitting all the pins. 3. A bowler should be able to estimate his timing. This is one way of showing respect to other bowlers. It is not appropriate to pick a ball that is already being used by another bowler. 6. Bowlers should allow a healthy competition among players by learning to compete with other players in a friendly way. They should cooperate with teammates by not wasting time during the game and participating eagerly in the game.
