Hula hoop

Hula hoop is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hula hoop rather than just read about it. In short: A hula hoop is a toy hoop that is twirled around the waist, limbs or neck. Hoops can also be used for hoop rolling, wheeled along the ground like a wheel with careful execution and practice.

Key takeaways

  • Hula hoop belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hula hoop to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hula hoop from memory before moving on to harder problems.

Reference excerpt

A hula hoop is a toy hoop that is twirled around the waist, limbs or neck. Hoops can also be used for hoop rolling, wheeled along the ground like a wheel with careful execution and practice. They have been used by children and adults since at least 500 BC. The modern hula hoop was inspired by Australian bamboo hoops. Joan Anderson witnessed Australian children playing with bamboo hoops while driving past in an automobile, naming it "hula hoop" after the Hawaiian hula dance and introducing it to the Wham-O toy company, who popularized the plastic version in 1958 and helped it become a fad. Hula hoops for children generally measure approximately 70 centimetres (28 in) in diameter, while those for adults measure around 100 centimetres (39 in). Traditional materials for hula hoops include willow, rattan (a flexible and strong vine), grapevines and stiff grasses. Commercial hoops are usually made of plastic tubing.

Origins Native American Hoop Dance is a form of storytelling dance incorporating hoops as props. These props are used to create both static and dynamic shapes, which represent various animals, symbols, and storytelling elements. The dance is generally performed by a solo dancer with multiple hoops. Before it was known and recognized as the common colorful plastic toy (sometimes filled with water or sand), the traditional "hula hoop" was made of dried willow, rattan, grapevines, or stiff grasses. Though they have been in existence for thousands of years, it is often incorrectly believed that they were invented in the 1950s. Author Charles Panati records a "craze" with the usage of wooden and metal hoops in 14th-century England. He reports that doctors treated patients who suffered pain, dislocated backs, and even heart failure from hooping. Panati also says that the name "hula" came from the Hawaiian dance in the 18th century, due to the similar hip movements. Hamleys, the world's oldest toy store, sold hula hoops when it opened its original shop in London in 1760.

Modern history The hula hoop gained international popularity in the late 1950s, when a plastic version was successfully marketed by California's Wham-O toy company. Cane hoops had been popular children's toys to be rolled on the ground and kept balanced for as long as possible. In 1957, children in the Norwegian town of Steinkjer began a fad described in the English press as "rock-rings", with the description being "These are huge cane rings which little girls swing round their bodies by moving their hips and arms." An August 7 news item described the origin as children buying cane rings after seeing ring jugglers at a circus that visited Steinkjer and added, "It wasn't long before most of the children in town had caught the 'wiggle-rock' craze, now it is all over Norway." In the same summer, schoolgirls in Australia were using the hoops and news came to the United States with the first reference to the toy as a "Hula hoop", described as "all the rage among the female small fry of Australia. This is old fashioned hoops with a difference. You don't roll them; you put them around your middle and by swinging the hips in a circular motion, you keep the hoop revolving— hence the name." According to The Playmakers: Amazing Origins of Timeless Toys by Tim Walsh, the bamboo hoop's path to plastic started in Australia when a Sydney teacher taught school students how to sway bamboo hoops in sports classes. Australia's Coles department stores then started selling bamboo hoops and demand soon outstripped supply. Coles then asked legendary toy man Alex Tolmer (also known as Alec), who founded toy company Toltoys, to help mass produce hoops. In 1957, Tolmer used Polyethylene which was stronger and less brittle than earlier plastics. The new lightweight plastic hoops sold in a variety of colors for less than $2. Toltoys sold 400,000 plastic hoops in Australia in 1957 alone. According to Tolmer's Melbourne-based son (David Tolmer) Toltoys already had a good working relationship with Wham-O in the United States. When Wham-O told Toltoys the hoop was too generic to warrant a royalty, Alex Tolmer instead asked the U.S. company to sponsor one bed in an Australian children's hospital. By 1958, Wham-O plastic hoops were being used in California and then the craze for hooping swept the United States and beyond. Joan Anderson (born Joan Constance Manning) coined the name "hula-hoop". She was visiting her birth country of Australia from the United States and saw people twirling bamboo hoops on their waists. She then had her mother ship one to the United States, with her husband Wayne introducing it to Wham-O's Arthur "Spud" Melin as the "hula-hoop" after the Hawaiian dance. Anderson insists that a deal with Wham-O was sealed with a "gentleman's handshake," but Melin would not contact them after it achieved success and did not credit them. Anderson sued Wham-O in 1960 for not paying them for hula hoop sales, with Wham-O arguing that they had not turned a profit despite high sales. Anderson settled for $6,000. On September 6, 1958, singer Georgia Gibbs appeared on US TV's The Ed Sullivan Show to sing "The Hula Hoop Song". Her last US top-40 hit, it competed with four other songs created in the wake of the huge fad. Richard Knerr and Melin of Wham-O updated the Toltoys design and manufactured 110 cm (42 in) diameter hoops from Marlex plastic. The earliest known advertisement was seen for the "Hula-Hoop by Wham-O" was seen on June 16, 1958 for "The Broadway" chain of department stores in Los Angeles, for sale for $1.98 (equivalent to $20 more than 60 years later). With giveaways, national marketing and retailing, a fad began in July 1958: twenty-five million plastic hoops were sold in less than four months, and sales reached more than 100 million units in two years. Carlon Products Corporation was one of the first manufacturers of the hula hoop. During the 1950s, Carlon was producing more than 50,000 hula hoops per day. Saddled with a glut of unwanted Hula Hoops, Wham-O stopped manufacturing the toy until 1965, when Knerr and Melin came up with a new twist: They inserted ball bearings in the cylinder to make a "shoosh" sound. The hoop was inducted into the National Toy Hall of Fame at The Strong in Rochester, New York, in 1999.

Worked examples

Example 1 — a first encounter with Hula hoop

Start with the simplest possible case. Write down what Hula hoop claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hula hoop before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hula hoop ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hula hoop

In research
Hula hoop appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hula hoop in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hula hoop is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s fads and trends, 1950s toys, Brands that became generic, so understanding it makes those chapters shorter.
In everyday life
Look for Hula hoop outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
