Tennis Balls: The Key Elements of Tennis Game
Tennis balls are famous not that much because of the sport as thanks to their bright look that gets them spotted in a second. They are usually orange, pistachio green or yellow and their diameter is 6.7 centimeters or 2.7 inches. Like in football, tennis balls are recognized by kids and adults alike and they are often part of children's games that have nothing to do with tennis as such. The balls and the rackets are the key elements that create the essence or the basis of any tennis game, although depend on other gear items too.
Tennis balls have a pretty long history. Back in the old days when tennis came into being, these balls were manufactured from leather and were stuffed with various materials like hair or wool. These old tennis balls were not the kind to bounce and make the game interesting as it is today. The Scots are the ones known to have manufactured these balls initially; they would use animal human hair, animal fur or wool to stuff the round container made of leather and tied with animal intestines instead of rope. Although to a modern mind this sounds less than rudimentary, the initial users were far from the vulcanized rubber balls we use today. The tennis balls variant between the organic material and the vulcanized rubber was the rubber core tennis ball that got popular in the 19th century, once people started playing tennis on lawns.
Today’s tennis balls are not made simply from rubber anymore. Chemicals added for rubber consistency are now widely used in the tennis balls design. This mixture of rubber and other chemicals makes about 80 percent of the entire ball. One of its peculiar ingredients is the felt which helps a great deal in rendering tennis balls certain properties like wind and the player’s striking resistance. The felt also has an important role in controlling the tennis bounce and the speed properties of the tennis balls.
Tennis balls can be either pressurized or pressureless. The distinction also has a great deal to do with how much the ball bounces. A pressurized ball will bounce more. The problem is that the bounce disappears in time. As for the pressureless balls, they increase in bounce and are considered more reliable. Presently, the appearance of all sorts of technologies makes it possible for all sorts of equipment to be under constant improvement and tennis balls are no different for the matter.
