A flying disc is a disc-shaped gliding toy or sporting item
that is generally plastic and roughly 20 to 25 centimetres (8 to 10 in) in
diameter with a lip, used recreationally and competitively for throwing and
catching, for example, in flying disc games. The shape of the disc, an airfoil
in cross-section, allows it to fly by generating lift as it moves through the
air while spinning. The term Frisbee, often used to generically describe all
flying discs, is a registered trademark of the Wham-O toy company.
The Frisbie Baking
Company of Bridgeport, Connecticut, made pies that were sold throughout New
England. Hungry college students soon discovered that the empty pie tins could
be tossed and caught, providing endless hours of game and sport. Many colleges
claim to be the home of ‘he who was first to fling’ what became the Frisbee,
but many attribute it to Yalies making a game of throwing the pie tin on The
Green.
Another tale of the first frisbie fling – in 1827, a Yale
undergraduate grabbed a passing
collection tray from the chapel and flung it out into the campus, thereby
becoming the true inventor of the Frisbee. This student’s supposed name? Elihu
Frisbie. This tale is often disputed
because the pie tins had “Frisbie” stamped on them.
The inventor of the Frisbee, Walter Frederick Morrison
(always known as ‘Fred’) was born on January 23, 1920.On his 37th birthday, on
January 23, 1957, he sold the rights to his invention to the Wham-O toy
company, which later gave it the name ‘Frisbee’.
Morrison had the frisbee idea as a teenager throwing lard
popcorn tin lids with his girlfriend.He later discovered that cake pans were
better than lard can lids and he developed a business called “Flyin’ Cake
Pans”.Later names he gave to the disc were Whirlo-Way, Flyin’ Saucer and Pluto
Platter.
The Wham-O company changed the name when it learnt that
students were calling them ‘Frisbie’ after pie tins from the Frisbie Pie
Company.Morrison, who died in 2010, was the uncle of Colonel Steve Warr, who is
the fifth highest-ranked pole-vaulter in the world aged 70-74.
The worldwide database of the European Patent Office lists
84 frisbee-related patents.These include an Underwater Frisbee Golf Disc
Locator and a Multipurpose Frisbee for Dogs.At his own request, Morrison was
cremated and his ashes moulded into frisbees for his family.
- Ultimate Frisbee ( International Game )
Now, they are many kind of activities that can be held with frisbee. One of it is Ultimate Frisbee which is kind of competition mainly held in US.Ultimate has come a long way since it's days as being
perceived as a counter-culture activity bore during the 1970's.
It's now a sport with an international governing body,
several tournaments, and it is likely to be added to the Summer Olympics.
- The end zones in Ultimate are twice as big as those in football
While covering almost the same amount of area as a football
field, the actual playing field of ultimate is thirty years shorter because
each end-zones being twenty-five yards deep.
On the international level, the end-zone size is shortened
to about twenty yards. Both fields are forty yards wide, whereas a football
field is around fifty-three and a half yards wide.

Everyone loves dolphins. They’re intelligent, inquisitive, playful creatures who have captivated people since the dawn of time.
But dolphins didn’t get to be everyone’s favorite aquatic mammal just by lounging around all day. Having to adapt to life in the harsh ocean environment requires some serious skills. As a result dolphins, have developed some incredible abilities that continue to amaze researchers.
- Sleeplessness
Everything needs sleep. The human world record holder, Randy
Gardner, stayed awake for 11 days straight. By the fourth day, he was hallucinating.
Not sleeping will eventually kill you and every other mortal creature with
higher brain functions—except dolphins, which have apparently found a way
around sleep. Baby dolphins actually forgot to sleep for the first month of
life—and so, therefore, do their parents.
The trick is that these amazing sea critters can shut half
of their brain off at a time. Scientists tested dolphin reactions without rest
for five days straight and their reaction time never slowed. Blood tests for
signs of stress or sleep deprivation turned up negative. Dolphins may be able
to do this indefinitely.
Another study showed that dolphins can use their sonar for
15 days straight with almost perfect accuracy. It makes sense that dolphins
evolved a way to keep an eye out for predators while they’re dozing in the open
ocean.
But the truly fascinating part about all of this is that tests showed visual information was being passed from the snoozing side to the active side. Even though they shut down half of their noggin at a time, the other half can take over all the functions. It’s almost as if they have two brains.

- Alien-like ( Awesome ) respiration system!
It turns out that dolphins are pretty good swimmers. The
bottlenose can hold its breath for 12 minutes and dive nearly 550 meters (1800
ft). Part of the reason dolphins can do this is because they’ve got incredible
lungs. Though they aren’t much bigger than our own, they’re much more
efficient.
With each breath, a dolphin exchanges 80 percent or more of
its lung air. We puny humans can only get out about 17 percent. Their blood and
muscles can store and transport more of that oxygen, too. This is because they
have more red blood cells, which in turn have greater concentrations of
hemoglobin than we do.

Even though you won’t find it on a map, the Bermuda Triangle
is a very real place. In the past there have been many stories of disappearing
ships, planes and people. Although there is a reasonable explanation for many
incidents, some are still a mystery.
The Bermuda Triangle is located off the coast of Florida
between Miami, Puerto Rico and the Bermudas. It covers about 500 000 square
miles of the Atlantic Ocean. It is also known as the Devil’s Triangle because
Bermuda was once called Islands of the Devils. The coasts around the island are
surrounded by dangerous reefs that ships ran into throughout the centuries.
Unusual events around the Bermuda Triangle go back to the
voyages of Christopher Columbus. He sometimes reported that compass readings
were wrong. Many journalists have tried to prove that a number accidents and
unusual things have happened in the region. Some cases show that there are no
explanations for them.
One of the best-known incidents is the disappearance of
Flight 19 during a training exercise of the US Navy. In December, 1945 five
American bombers left Fort Lauderdale, Florida on a routine mission. 14 crew
members disappeared after sending several radio messages. When a rescue plane
went to search for the Navy bombers it also vanished.
What went wrong during the mission is not fully known.
Compasses showed wrong directions and visibility was bad so the flight leader
decided to navigate by landmarks which he saw below. Then there was a sudden
storm and radio contact broke off. Wrecked parts of Flight 19 have never been
recovered.
Ships have also disappeared in the Bermuda Triangle. Among
them is the Mary Celeste, an American merchant ship, in 1872. The ship was
sailing from New York to Genoa, but was later found off the coast of Africa
without any crew members on board. Although there is no evidence that the Mary
Celeste even entered the Bermuda Triangle there are many who connect its
mysterious disappearance with the area.
There are many theories about why so many airplanes and
ships have disappeared in the Bermuda Triangle. Some suggest that there are
special magnetic fields that cause unknown physical forces. Others say that the
lost continent of Atlantis sank in the region causing mysterious events. There
is even a theory about unknown chemicals in the waters of the Atlantic.
Some experts, however, point out that the region north of
the Caribbean is not as safe as it may seem. It is one of two places on Earth
where the compass points to the geographic North Pole. It is also a region in
which the weather is unpredictable and where storms can emerge quickly. There
are strong currents because of shallow places and deep trenches in the ocean.
These factors can confuse even experienced sailors.
Over 1,000 people were killed in The Bermuda Triangle during
the 20th century. Scientists have concluded that this figure is normal and most
disappearances have a logical explanation. The myth of the Bermuda Triangle,
however, remains.
