How Do Sword Swallowers Swallow Swords?

Swallowing food involves a series of muscle contractions, both voluntary and involuntary. Swallowing a sword requires no actual swallowing, but the complete opposite: the deliberate relaxation of the upper gastrointestinal (GI) tract.

First, the sword swallower tilts their head back and extends their neck to line up their mouth with their esophagus and straighten the pharynx. Relaxing their throat, they line the sword up with the path of their GI tract and move the blade into and through the mouth, pharynx and upper esophageal sphincter and into the esophagus. As the sword makes its way through the GI tract, it straightens out esophagus' curves and sometimes, if an especially long sword is used, passes through the gastroesophageal junction (lower esophageal sphincter) and into the stomach.

It sounds easy, but sword swallowing isn't something you can learn to do in an afternoon. Learning to relax the GI tract takes practice, and lots of it. Furthermore, a sword swallowing performance usually goes better if the swallower can make it look like it isn't the worst thing that ever happened to them. To see how difficult that can be, touch the back of your throat right now.

Not pleasant, is it? Now imagine cramming a long, cold and rigid sword down there, and even further, while keeping a straight face.

Beyond the physical process of relaxing the GI tract and carefully inserting the sword, the feat is accomplished by practice, attaining a mind-over-matter attitude and maintaining calm and focus during the performance.

Some sword swallowing facts:

"¢ During the development of endoscopy, the examination of the interior of the human body using a scope, researchers often worked with sword swallowers because their bodies were able to accommodate the rigid instruments.

"¢ The Coney Island Sideshow School offers organized sword swallowing classes.

"¢ Sword swallowing originated about 4000 years ago in India among fakirs and shamans who developed it as demonstration of their invulnerability, power and connection with the gods.

"¢ Sword swallowing came to America in the early 1800s and began gaining popularity after swallowers performed at the 1893 Chicago World's Fair.

"¢ The Sword Swallowers Association International (SSAI) proclaimed February 28th, 2008 as International Sword Swallower's Day "to raise awareness of sword swallowers around the world." (February is National Swallowing Disorders Month)

"¢ Sword Swallowers refer to irritation of the throat due to performance as a "sword throat."

"¢ Red Stuart recently set the record for most swords swallowed simultaneously when he swallowed 34 at the 2008 Philadelphia Tattoo Convention on April 19, 2008.

"¢ In 2003, Matty "Blade" Henshaw set the record for most swords swallowed in a year: 3782.

"¢ "The Sword of Swords" has been swallowed by 33 different performers since 1994, when it was made by Thomas Blackthorne as an icon that could link the far-flung members of the sword-swallowing world.

"¢ In carny lingo, sword swallowers are called "blade glommers" or "steel slurpers."

How Much Is the Earth Worth?

Our home planet may be the most precious place we know, but it isn't priceless. The Earth's resources and the value it offers to humans add up to some unknown, tangible cost. The species may never have to worry about buying or selling the world, but thinking of it in terms of concrete numbers can help us better understand its value. Now, as Treehugger reports, one scientist has developed a special formula that allows us to do just that.

According to the calculations of Greg Laughlin, an assistant astronomy and astrophysics professor from the University of California, Santa Cruz, the Earth is worth roughly $5 quadrillion (or $5,000,000,000,000,000). He came up with that price after gauging the planet's mass, temperature, age, and other factors that directly correlate to its ability to sustain life.

To emphasize just how valuable the Earth is, Laughlin also estimated the worth of other planets in our solar system. Our nearest neighbor Mars costs about the same as a used car at $16,000. That's a fortune compared to Venus, which he appraised at the meager value of one cent.

Laughlin doesn't expect these numbers to have applications in the real world. Rather, he hopes they will inspire people to better appreciate the only home they know. He's not the first person to put a massive, hypothetical price tag on something just for fun. The cost of the Death Star from Star Wars has been calculated at $852 quadrillion—many times Laughlin's estimate for Earth.
