What are bowling balls made of?

In the 1960s, hard rubber balls were king. \n\nPolyester balls stole the scene in the '70s. (Most of the "house balls" in your local bowling alley are of the polyester variety.) \n\nThe '80s saw the dawn of the urethane ball. \n\nUrethane balls matured in the early '90s with the introduction of reactive urethane. \n\n\nUrethane balls were introduced in the early eighties. This material is more durable than plastic, and has more surface friction and better contact with the lane than plastic does. This ball is usually the next step up from plastic and will allow you to play a bigger hook to the pocket with less deflection compared to the plastic ball. There are a few more options available as far as the shape of the core. This will allow the ball to flare a little more, adding more hook potential to the ball. These balls today are not readily available and may need to be specially ordered\n\nReactive resin balls were introduced in the early nineties. Manufacturers created this coverstock by putting additives in the urethane formula to create a "tacky" feel to the ball. Resin balls are also known as reactive urethane. This created a much bigger reaction in the bowling ball. This was especially noticed toward the back end of the lane in front of the pins. Bowlers are able to create severe angle to the pocket. When this ball was introduced, it was the start of a whole new revolution to the game. Bowlers with less hand action were now able to compete with the big crankers. Balls with this new coverstock was even nicknamed "cheater balls" This was because this new cover seemed to have no respect for the oil, and would hook back to the pocket from almost anywhere. You now saw the straighter players using the same angle to the pocket that the crankers would play. The scoring pace has picked up an incredible amount since the invention of this material. Because this cover reacts so much harder, it will also be a little more erratic at times as well. The nature of this cover is to skid more through the oil and react very sharply to the drier part of the lane. There is a much bigger variety of core shapes with this cover, and technology has allowed for this material to get more predictable as each generation of new resin is made. The range of hook is much greater and the balls are able to be more finely tuned to the bowler's game now.

Different materials are chosen for different parts of the club based on their mechanical properties, such as strength, elasticity, formability, impact resistance, friction, damping, density, and others.\n\nClub heads for drivers and other woods may be made from stainless steel, titanium, or graphite fiber-reinforced epoxy. Face inserts may be made from zirconia ceramic or a titanium metal matrix ceramic composite. Oversize metal woods are usually filled with synthetic polymer foam. Traditionalists can even buy woods that are made of real wood. Persimmon, laminated maple, and a host of exotic woods are used. Wood club heads are usually soaked in preserving oil or coated with a synthetic finish like polyurethane to protect them from moisture.\n\nClub heads for irons and wedges may be made from chrome-plated steel, stainless steel, titanium, tungsten, beryllium nickel, beryllium copper, or combinations of these metals. Heads for putters may be made of all of the same materials as irons, plus softer materials like aluminum or bronze, because the velocity of impact is much slower when putting.\n\nClub shafts may be made from chrome-plated steel, stainless steel, aluminum, carbon or graphite fiber-reinforced epoxy, boron fiber-reinforced epoxy, or titanium. Grips are usually made from molded synthetic rubber or wrapped leather.\n\nDesign\nThe rules of the United States Golf Association (USGA) have only a few brief paragraphs regarding the design of golf clubs. There are no restrictions on weight or materials, and only a few restrictions on dimensions. Shafts must be at least 18 in (457 mm) long. The distance from the heel to the toe of the head must be greater than the distance from the face to the back of the head. The cross-sectional dimension of the grip must not be greater than 1.75 in (45 mm) in any direction. Of all the rules, however, the most important one requires that the club ''shall not be substantially different from the traditional and customary form and make."\n\nIt is this last rule that sometimes gives club designers the fits. It means, for example, that club heads may not have features like aiming fins or holes to reduce aerodynamic drag. Shafts may not have flexible joints, and so forth. In short, anything that is not "traditional and customary" is not allowed. All new club designs must be submitted to the USGA for review and approval before they may be used in tournament play.\n\nWithin the USGA guidelines, many new features have been incorporated into golf clubs. Using computer-aided design programs and mathematical models of club and ball dynamics, designers have learned to utilize new materials, redistribute weight, and alter the general shape of the club in an attempt to help both professional golfers and weekend duffers improve their games.\n\nOne common feature of modern irons is perimeter weighting, which places most of the club head weight around the edges, leaving the center with less material. This added mass reduces the amount of club twist when the ball is struck towards the edge of the club, rather than in the center. The effect is to increase the size of the effective hitting area, or the "sweet spot" as golfers call it. The hollow oversize metal heads on some drivers have the same effect.\n\nAnother design feature of some modern clubs is the offset head, where the striking face is located to the rear of the centerline of the shaft. This places the golfer's hands slightly ahead of the ball at impact, which tends to square the club face and give better direction control.\n\nOth

Bocce. There is also a very similar game, lawn bowling, that uses balls that are made the same as Bocce balls, except they are asymmetrical to cause them to curve when rolled.

Rubber.  Players used to use rubber balls, but they bounced and rolled too much.  With experimentation, they found that slicing the top and bottom off created a puck that slid across the ice and was easier to control.

Most modern balls have 32 panels of waterproofed leather or plastic: 12 regular pentagons and 20 regular hexagons. Older balls have 18 panels.\n\nHope this helps!

front desk, if they serve food, food counter, then there are the cleaners, machine tecs, pin setters,some places have pro shops where they drill the bowling balls, some have bars, servers,lane cleaners. i hope this helps you out. most bowling alleys have all of this it all depends on what your bowlin alley has to offer.

It depends highly on your play style. If you're used to throwing house balls, which are plastic with a static core, then it'll take a lot of practice to get used to the custom balls. They have what's called a "dynamic" core; it's smaller, more dense, and helps impart spin on the ball to create the hook you see professional bowlers throwing. Choose a comfortable weight; remember that lighter balls won't have the same power through the pocket as heavy ones, but heavy balls are harder to throw and sometimes control. In the long run, choose a ball that just -feels- right to you. Trust a bowling alley's pro shop owner with the decisions he gives for you, and ask the guy a LOT of questions, because he'll know the answers.

I couldn't find any explanation for your question but I found an interesting article about tennis balls:\n\nIn theory, there could be 24 different kinds of balls. Tennis balls come in four speeds, three types of felt, and two basic means for producing bounce, but some of these combinations are illogical or simply not produced, leaving 16 that you might find if you looked hard enough and only four that you'd find in most pro shops:\n\n    * pressureless, medium speed, extra duty felt\n    * pressurized, medium speed, regular felt\n    * pressurized, medium speed, extra duty felt\n    * pressurized, slow speed, extra duty felt \n\nThe numbers on the balls are only there to help people distinguish their balls from another can of the same brand on an adjacent court.

Not sure what they are made of, but I do know what they play on them for sure. PLAY MISTY FOR ME as featured in that Clint Eastwood movie. (ps. I can't remember the name of the movie but I'm sure you clever lot out in Answers land know)

Golf Balls\nThe construction of the golf ball has changed a lot the past 10 years I'm going to cover 3 areas\n\n1.  Harder golf balls, some call them two piece, they are promoted for distance - these balls will go further than the other types.  The ball will hook or slice less and  will not stop on the green as well as the other types.  This ball is harder to fade or drawl.  This ball will bounce higher than the other balls if dropped on a hard surface\n\n2.  This ball is built for feel but has a harder cover - You get good distance but not as good as the 1st.  The ball will stop on green a little better and will move around a little more.  This ball will have some spin on it.\n\n3.  Softer ball - This ball has more feel to it.  The ball spins so it will hood or slice more.  The ball stops on the greens.  You can move the ball around.  This ball is very pricey and not as durable.

Cricket balls are made from a core of cork, which is layered with tightly wound string, and covered by a leather case with a slightly raised sewn seam. The covering is constructed of four pieces of leather shaped similar to the peel of a quartered orange, but one hemisphere is rotated by 90 degrees with respect to the other. The "equator" of the ball is stitched with string to form the seam, with a total of six rows of stitches. The remaining two joins between the leather pieces are left unstitched.\n\nFor men's cricket, the ball must weigh between 5.5 and 5.75 ounces (155.9 and 163.0 g) and measure between 8 13/16 and 9 in (224 and 229 mm) in circumference. Balls used in women's and youth matches are slightly smaller.\n\nCricket balls are traditionally dyed red, and red balls are used in Test cricket and First-class cricket. White balls were introduced when one-day matches began being played at night under floodlights, as they are more visible at night. Many one-day matches are now played with white balls. Other colours have occasionally been experimented with, such as yellow and orange for improved night visibility, but the colouring process has so far rendered such balls unsuitable for professional play because they wear differently to standard balls.The white ball has been found to swing a lot more during the first half of the innings than the red ball.It also deteriorates faster than the red ball.

go to a specialty sports store like dicks or garts. They have balls made of other materials that are lighter.

SuperBall (originally Super Ball) is a toy manufactured by Wham-O®. It is an extremely elastic ball made of Zectron®, which contains the rubber polymer polybutadiene and sulfur, having a high coefficient of restitution. When it is dropped from shoulder level onto a hard surface such as concrete, it rebounds to about 90% of the original height. "Superball" has also become something of a generic name for any similarly high-bouncing rubber ball.\nThe original Super Ball was invented by chemist Norman Stingley in his spare time in 1965.\n\nWhen Lamar Hunt saw his daughter playing with a Super Ball, it inspired him to name the new AFL-NFL World Championship Game the Super Bowl

Silica; it's what makes glass, and ceramics have insulative properties. Other than that, it would be petroleum products such as plastics, and vinyls. Rubber comes from a plant.

Cricket bats are generally made from English Willow, a very hard wood that doesn't split or crack easily.  The choice of willow is critical to the quality of the bat.  Some bats are made by machines, while the best are made by master cricket bat makers who individually hand craft and hand shave the cricket bats they make.  The hand made bats are usually of better quality (last longer, better smack to the impact of the ball), although some well made machined bats exist when the right willow is selected.
