2 Hula Hoops and a Skateboard




2 Hula Hoops and a Skateboard







The hula hoop is an ancient invention - no modern company and no single inventor can claim that they invented the first hula hoop. The Greeks used hooping as a form of exercise.

Older hoops have been made from metal, bamboo, wood, grasses, and even vines. However, modern companies "re-invented" their own versions of the hula hoop using unusual materials, for example; plastic hula hoops with added bits of glitter and noise makers, and hoops that are collapsible.

Around 1300, hooping came to Great Britain, homemade versions of the toy became very popular. In the early 1800s, British sailors first witnessed hula dancing in the Hawaiian Islands. Hula dancing and hooping look somewhat similar and the name "hula hoop" came together.


Richard Knerr and Arthur "Spud" Melin founded the Wham-O company which helped popularize another ancient toy, the frisbee.
Knerr and Melin started the Wham-O company from their Los Angeles garage in 1948. The men were marketing a slingshot originally invented for training pet falcons and hawks {it slung meat at the birds). This slingshot was named "Wham-O" because of the sound it made when it hit the target. Wham-O also became the company's name.

Wham-O has become the most successful manufacturer of hula hoops in modern times. They trademarked the name Hula Hoop ® and start manufacturing the toy out of the new plastic Marlex in 1958.

Twenty million Wham-O hula hoops sold for $1.98 in the first six months.

Trivia
•Japan once banned the hula hoop because the rotating hip action seems indecent.
•On June 4, 2005, Australian Kareena Oates set a Guinness world record for hula hooping - with 100 hoops for three full revolutions.
•101 hoops were spun by Alesya Goulevich of Belarus on June 11, 2006
•105 hoops were spun by Jin Linlin of China on October 28, 2007.
•The world record for the largest Hula Hoop (by circumference) spun was set by American Ashrita Furman at 51.5 feet on June 1, 2007.

Skateboarding was first started in the 1950s, when all across California surfers got the idea of trying to surf the streets. No one really knows who made the first board -- instead, it seems that several people came up with similar ideas at the same time. Several people have claimed to have invented the skateboard first, but nothing can be proved, and skateboarding remains a strange spontaneous creation.
These first skateboarders started with wooden boxes or boards with roller skate wheels slapped on the bottom. Like you might imagine, a lot of people got hurt in skateboarding's early years! It was a sport just being born and discovered, so anything went. The boxes turned into planks, and eventually companies were producing decks of pressed layers of wood -- similar to the skateboard decks of today. During this time, skateboarding was seen as something to do for fun after surfing.

In 1963, skateboarding was at a peak of popularity, and companies like Jack's, Hobie and Makaha started holding skateboarding competitions. At this time, skateboarding was mostly either downhill slalom or freestyle. Torger Johnson, Woody Woodward and Danny Berer were some well known skateboarders at this time, but what they did looked almost completely different from what skateboarding looks like today! Their style of skateboarding, called "freestyle", is more like dancing ballet or ice skating with a skateboard.

Then, in 1965, skateboarding's popularity suddenly crashed. Most people assumed that skateboarding was a fad that had died out, like the hoola hoop. Skateboard companies folded, and people who wanted to skate had to make their own skateboards again from scratch.

But people still skated, even though parts were hard to find and boards were home made. Skaters were using clay wheels for their boards, which was extremely dangerous and hard to control. But then in 1972, Frank Nasworthy invented urethane skateboard wheels, which are similar to what most skaters use today. His company was called Cadillac Wheels, and the invention sparked new interest in skateboarding among surfers and other young people.

In the spring of 1975, skateboarding took an evolutionary boost toward the sport that we see today. In Del Mar, California a slalom and freestyle contest was held at the Ocean Festival. That day, the Zephyr team showed the world what skateboarding could be. They rode their boards like no one had in the public eye, low and smooth, and skateboarding was taken from being a hobby to something serious and exciting (Read more about the history of Dogtown and the Zephyr team). The Zephyr team had many members, but the most famous are Tony Alva, Jay Adams and Stacy Peralta.

But that was only the first big jump in the evolution of skateboarding - continue to the next page for the rest of the history...

The Zephyr team, and all the skaters who wanted to be like them, also made skateboarding even more edgy in the public eye, and added a strong anti-establishment sentiment t

Timing Belt Urethane/Polyeste, Single-Sided, 0.0816










Nylon Covered Fiberglass Reinforced Neoprene One-Sided Timing Belts. Evenly spaced teeth on the inside circumference of One-Sided Timing Belts help avoid the slippage or creep encountered with simple flat belts. Important for applications involving a definite motion sequence or indexing, these belts are capable of transmitting high torque and can withstand rapid accelerations. The trapezoidal tooth profile concentrates stress near the root of the tooth, promoting positive grip and uniform speed transmission. Made of Nylon Covered Fiberglass Reinforced Neoprene, these belts require no lubrication, are resistant to chemicals, and have very low stretch with excellent strength and dimensional stability. Also, since a narrower belt will handle a larger load, they are generally of lower cost than other drive mediums.
