Nearly 300 million frisbees have been sold since their introduction 40 years ago, for both organized sports and recreational play. According to Mattel, 90% of Americans have played with this flying toy at one time or another, translating to 15 million people enjoying the sport every year. Now, older versions of this toy have become collectors' items worth hundreds of dollars or more.

The frisbee's origins actually go back to a bakery called the Frisbie Pie Company of New Haven, Connecticut, established by William Russell Frisbie after the Civil War. The bakery stayed in operation until 1958, and during this period, the tossing of the company's pie tins, first by company drivers and later by Ivy League college students (some say it was cookie tin lids), led to frisbie becoming a well known term describing flying disc play in the Northeast.

Several years after World War II, Walter Frederick Morrison—the son of the inventor of the automobile sealed-beam headlight—and his partner Warren Franscioni, investigated perfecting the pie tin into a commercial product. First, they welded a steel ring inside the rim to improve the plate's stability, but without success. Then, they switched to plastic and the frisbee as we know it today was born.

The initial design, which incorporated six curved spoilers or vanes on the top, was vastly improved in 1951 and thus became the Pluto Platter, the first mass-produced flying disc. This design, which incorporates a slope on the outer third of the disc, has remained part of the basic design to this day. The Morrison Pluto Platter had the first true cupola (cabin in Morrison's terns) and resembled the concept of flying saucers (UFOs) depicted during this period complete with portholes. In 1954, Dartmouth University held the first frisbee tournament, involving a game called Guts.

The founders of Wham-O, a California toy company, became interested in this flying disc in 1955 and about a year later began production after acquiring the rights from Morrison. The name was changed to frisbee after the company heard about the pie tin game on the east coast called Frisbie-ing. (Wham-O first marketed the Pluto Platter in January of 1957, but didn't add the word frisbee until July 1957.) In 1959, the first professional model frisbee was produced.

It wasn't until the early 1960s when frisbees became the rage and soon organizations became established to promote sporting events, including the International Frisbee Association and the Olympic Frisbee Federation. The first game of Ultimate Frisbee, a sport of both distance and accuracy similar to football, was played in 1968 at a New Jersey high school. Now, it is played at nearly 600 colleges and in 32 countries. In 1969, the U.S. Army even invested $400,000 to see if flares placed on frisbees would stay aloft but without success.

During the 1970s, several organizations were formed to promote specific events, including disc golf, freestyle, and Guts. The Professional Disc Golf Association (PDGA) now has over 14,000 members in 20 countries playing on over 700 frisbee golf courses. Today, 40,000 athletes in 35 countries compete in Ultimate Frisbee. The formation of such associations led to world championships being held during the 1980s.

Today, organized competitions in nine different events (including disc golf and freestyle) take place each year around the world, under the auspices of the World Flying Disc Federation (WFDF). Established in 1984, WFDF has member associations in 22 countries and provisional members in an additional 28 countries. During Operation Desert Shield in 1991, frisbee was used to boost the morale of the 20,000 U.S. soldiers on duty in Saudi Arabia.


Manufacturers of frisbees use computer aided design software to create a model. A prototype is then made to test the design. Sometimes, a wind tunnel and other sophisticated methods are used to test flying characteristics, depending on the type of frisbee. Manufacturing tolerances within a few thousandths of an inch are now incorporated into the design.

Designers are always looking for new ways to manipulate the physical properties that dictate flight characteristics by changing the design or shape in order to improve lift, drag, spin, angular momentum, torque and other forces that affect how an object flies. For instance, adding a small lip and concave edge to a disc greatly increases its stability in flight.

A major obstacle disk designers must overcome is this instability caused by gyroscopic precession, the tendency of spinning objects to roll right or left in flight, depending on the direction of their spin and where they get their aerodynamic lift. The closer the disk's center of gravity remains to its center of lift, the more stable and straight the flight.

As a spinning disk flies, its center of lift is near the front, or leading edge, of the disc and tends to pitch the disc upward. Because of the spin, much of the lifting force on a point near the disc's edge does not exert itself until about a quarter of a revolution later. Such gyroscopic precession pushes the disc up on the side, causing a sideways roll. This is why frisbees, which typically are thrown backhand to spin clockwise as viewed from the top, tend to roll left from the thrower's perspective in flight.

Once in the air, lift and angular momentum act on the frisbee, giving it a ballet-type performance. Lift is generated by the frisbee's shaped surfaces as it passes through the air. Maintaining a positive angle of attack, the air moving over the top of the frisbee flows faster than the air moving undemeath it.

Under the Bemoulli Principle, there is then a lower air pressure on top of the frisbee than beneath it. The difference in pressure causes the frisbee to rise or lift. This is the same principle that allows planes to take off, fly, and land. Another significant factor acting upon the frisbee's lift is Newton's Third Law. It states that for every action there is an equal and opposite reaction. The frisbee forces air down (action) and the air forces the frisbee upward (reaction). The air is deflected downward by the frisbee's tilt, or angle of attack.

Spinning the frisbee when it is thrown, or giving it angular momentum, provides it with stability. Angular momentum is a property of any spinning mass. Throwing a frisbee without any spin allows it to tumble to the ground. The momentum of the spin also gives it orientational stability, allowing the frisbee to receive a steady lift from the air as it passes through it. The faster the frisbee spins, the greater its stability.

Raw Materials

Frisbees have been made out of a thermoplastic material called polyethylene since the early 1950s. Polyethylene is the largest volume polymer consumed in the world. This material is derived from ethylene, a colorless, flammable gas. This gas is subjected to elevated temperatures and pressures in the presence of a catalyst, which converts the gas into a polymer. Other ingredients that may be added include colorants, lubricants, and chemicals to improve dimensional stability and crack resistance.

The Manufacturing

To make a frisbee, a high-speed process called injection molding is used, which is based on the injection of a fluid plastic material into a closed mold, usually of the multi-cavity type. Once in the mold, the plastic is cooled to a shape reflecting the

cavity. Since complex shapes can be made using this process, minor trimming after removal from the mold is the only other finishing required. Because of these advantages, this process is used to manufacture a wide range of products, from various toys to automotive bumpers.

A molding machine equipped with a hopper, heated extruder barrel, reciprocating screw, nozzle, and mold clamp is typically used. This machine heats the plastic until it is able to flow readily under pressure, pressurizes this melt to inject it into a closed mold, holds the mold closed both during injection and solidification of the material, and opens the mold to allow removal of the solid part.

Quality Control

The weight is one of the most important properties and is automatically controlled during the injection molding process by the screw on the machine that pushes the proper amount of material into the mold. Another important property for golf frisbees is flexibility, which is tested by putting a weight on the edge of the disc and measuring the degree it bends. The PDGA only needs to test one sample of a new golf disc for flexibility.


There is usually little waste produced during the manufacturing process. Sometimes after the frisbee is removed from the mold, it has excess material, called flash, around the edge. This is trimmed off, sent to a regrinding machine and then mixed with the virgin material. Other frisbees may be rejected if they are not the correct weight or have deco-rating defects. After the decoration is removed, by either cutting or by using a solvent depending on the application method, the rejects are also recycled in a similar way.

The Future

The frisbee is expected to dominate the twenty-first century as one of the great sports and pastimes. Frisbee sports should continue to grow, as well as collector groups interested in preserving its history. Though other flying toys have come onto the market—such as boomerangs, cylinders, and rings—the flying disc will continue to provide more hours of entertainment to people around the globe than probably anything else ever invented.

Disc golf specifically is experiencing record growth. In each of the last three years the number of courses in the United States alone has increased by 10%. Such growth should continue since there are still many areas of the country that are not yet aware of disc golf and the benefits it offers.

Also, frisbee may some day be an Olympic sport. For a sport to be eligible for the Olympics, it must be played for two years in at least 50 countries. Ultimate Frisbee is already played in 35 countries and its popularity is growing, along with other frisbee sports.
