Obviously it is not a hula hoop but here’s some trivia…
A hula hoop is a toy hoop that is twirled around the waist, limbs or neck. Although the exact origins of hula hoops are unknown, children and adults around the world have played with hoops, twirling, rolling and throwing them throughout history. Hula hoops for children generally measure approximately 71 centimetres (28 in) in diameter, and those for adults around 1.02 metres (40 in). Traditional materials for hoops include willow, rattan (a flexible and strong vine), grapevines and stiff grasses. Today, they are usually made of plastic tubing.
Hula hooping has been a type of exercise and play since 500 BCE to the 21st century. Before it was known and recognized as the common colourful plastic toy (sometimes with water inside the actual hoop), it used to be made of dried up willow, rattan, grapevines, or stiff grasses. These materials from different places of the world represents on how despite the lack of communication and resources the ancient world had compare to today, various cultures around the globe unknowingly shared the same idea and joy for the hula hoop. Even though the toy has existed for thousands of years, it is often misunderstood as being invented in the 1950s.
In the 14th century in England, hoops were later extended to adult audiences and were popular for recreation and religious ceremonies. According to their medical records from that era, doctors treated and encouraged patients with dislocated backs and heart attack victims to use this winding exercise. In the same period, the term “hula” was added to the toy name due to the experiences of some British soldiers who travelled to the Hawaiian Islands. During their stay, the soldiers noticed and realized the resemblance of the movement of the hips with the traditional hula dances to the movements of people that go hooping.
The hoop gained international popularity in the late 1950s when a plastic version was successfully marketed by California’s Wham-O toy company. In 1957, Richard Knerr and Arthur “Spud” Melin, starting with the idea of Australian bamboo “exercise hoops”, manufactured 1.06 metre (42 in) hoops with Marlex plastic. With give-aways and national marketing and retailing, a fad was started in July, 1958; twenty-five million plastic hoops were sold in less than four months, and in two years sales reached more than 100 million units. Carlon Products Corporation was one of the first manufacturers of the hula hoop. During 1950s when the hula hoop craze swept the country, Carlon was producing more than 50,000 hula hoops per day.
