The Official Shotgun Rules

Posted by Miss Cellania in Everything Else on November 4, 2009 at 10:39 pm

I have four kids who all want to sit in the front passenger seat as I drive. There is an elaborate set of rules they must follow to decide who gets the honor of “riding shotgun”.

You must say the word “Shotgun” to stake your claim on Shotgun. This must be done clearly and loud enough so that at least one other to-be occupant of the vehicle can hear you. No variations of this word are acceptable. After you have rightfully called Shotgun, you have exclusive rights to Shotgun for that ride. However, if no one hears you call Shotgun it is still fair game for everyone.

But that’s just the beginning! There are many more rules to learn, such as the importance of having your shoes on when you yell “Shotgun!” and the crucial “hand on the door” rule. Link -via Bits and Pieces

A Counterfeit Penny Made of Gold

Posted by Miss Cellania in Arts & Crafts, Money & Finance on November 4, 2009 at 10:16 pm

Seattle artist Jack Daws made eleven pennies by casting them from 18 karat gold and plating them with copper. One of those pennies was sold for $1,000 as a work of art. Another penny was spent at a news stand in Los Angeles. Yes, Daws sent one of the pennies into circulation in 2007 as a counterfeit -on purpose. He expected never to see it again. Over two years later, a graphic designer from Brooklyn noticed a golden gleam on a penny she was given as change. She put it away to investigate later, as she was a fan of unusual coins.

Then recently, while doing research about a 1924 Mercury-head dime, she remembered the penny and typed “gold penny” into Google, which returned information on science experiments to give a penny a gold color. She added “1970” and found an item about how Mr. Daws had put a 18-karat gold penny, dated 1970 with no mint mark, into circulation. It was heavier and smaller than a real penny.

In disbelief, she weighed the penny on a digital scale. It came in at three grams, one gram more than similar pennies from 1970. And it was slightly smaller than a normal penny, owing to the shrinking after the casting process.

She traced Mr. Daws’s phone number through the gallery and left him the message. When he called back, he knew it had to be his penny as soon as she described it to him.

Reed will keep the penny as a work of art. How many other hands did the gold coin pass through before she found it? We will probably never know. Link -Thanks, Bill!

The Redundant Photography of Fred Lebain

Posted by Johnny Cat in Pictures, Travel & Places on November 4, 2009 at 4:49 pm

fred06Photo: Fred Lebain

French photographer Fred Lebain took a trip to New York City and took a series of photos around town.  He then revisited those sites after printing out huge poster versions of his shots.  Then he carefully re-aligned the shots to incorporate his previous image into a new, dynamically interesting one.

these postcard images show lebain’s preference for particular areas of the city,
telescoping his views – a time parallax representing the days which separate the two shots -
and superimposing his vision of new york. hands, feet or a pair of jeans can be seen…
like surrealistic winks, indicating that the photographer is not alone in his mission.

Pop Culture Alignment

Posted by John Farrier in Movies & SciFi, Toy & Video Games on November 4, 2009 at 4:12 pm

This chart shows the moral alignments of nine pop culture characters using the Dungeons & Dragons alignment system. Rorschach as Chaotic Good? I think that Chaotic Neutral is more likely. And Neutral Good for John Locke at best.

Top row, left to right: John Locke of Lost, Dwight from Sin City, Rorschach of Watchmen.
Middle row: Indiana Jones, Niko Bellic of Grand Theft Auto 4, Tyler Durden of Fight Club.
Bottom row: Darth Vader, Anton Chigurh of No Country for Old Men, and the Joker.

I’m not sure who’s responsible for this chart — it’s been floating around the net. I’ll edit with a photocredit when someone claims responsibility.

Iron Age Gold Treasure Found in Scotland

Posted by Minnesotastan in Everything Else on November 4, 2009 at 3:48 pm

Scottish treasureA young man, using his metal detector for the first time, walked about seven steps from his car and got a signal.

The four gold Iron Age neck ornaments, or torcs, date from between the 1st and 3rd Century BC and are said to be worth an estimated £1m… The find is the most important hoard of Iron Age gold in Scotland to date.

Neatorama has previously posted stories about a Viking hoard and an Anglo-Saxon hoard found in the British Isles.  One factor that favors the discovery and preservation of these archeological treasures is the Treasure Act of 1996, an Act of Parliament that requires treasure hunters to turn in their finds to local authorities, but then guarantees them monetary compensation based on a market value of the treasure.  In many countries without such laws, finds such as these would be sold on the black market or melted down for bullion, destroying the remarkable artistry of the pieces.  The Treasure Act does not apply in Scotland, where this was found, but indications are that this fellow will be richly compensated in order to encourage others to report their discoveries.

At the BBC link the other pieces can be seen in a brief video.

Luggage That Turns Into a Couch

Posted by John Farrier in Arts & Crafts on November 4, 2009 at 3:34 pm


Photo:dezeen

Dutch designer Erik De Nijs created Suited Case — a collection of four functional suitcases that can be linked together in the form of a couch. His goal was to give travelers a taste of home while away:

This concept came from a research on nostalgia during travelling. When a familiar object from home is taken with you on a trip you feel much more at ease. And which object is more familiar then your own comfortable couch.

The fabrics which are used to cover the suit cases emphasize the homely feeling. I searched for a combination of fabrics which amplify each other and which create a prominent image. By using prints on the large luggage and the pad on the hand luggage I tried to put down a lively picture.

The work will be on display at the upcoming Dutch Design Week in Eindoven. You can view more pictures at the link.

Neatorama's Last Mystery Sale

Posted by Alex in Neatorama Only on November 4, 2009 at 1:38 pm

Hello everyone! As you can probably tell by the banners on the blog, we’re having a Mystery Sale on Neatorama. The proceeds help support the blog and our fledgling shop (thank you!)

For those of you who don’t know anything about it, the Mystery Sale offers an item you can buy for $9.95. What is it? We won’t tell you – that’s the whole point of the sale!

But we can tell you that it’s going to be a physical product (or combination of products) worth AT LEAST $9.95. It’ll be new and a fun "Neatorama" item.

You can buy more than 1 Mystery Item in a single order, in which case we’ll make sure that you get different items. You can even get them gift-wrapped so you can cross Christmas shopping off your list early this year.

We’re working on a new platform for Neatorama’s online shop, and the new one probably won’t be compatible with future Mystery Sale. I’m 99.9% sure that this will be the last Mystery Sale we’ll have (if not ever, then for a very long time) so grab yours today before it’s gone!

Man Stabbed Self to Hide Skateboarding Accident

Posted by Alex in Crime & Law on November 4, 2009 at 1:37 pm

Aaron Siebers, 27, had a problem. He was skateboarding one afternoon, fell, and ripped his Blockbuster-issued khakis. Worried about getting "written up," Aaron hatched a criminally (not so) brilliant plan:

Instead of just calling in sick, he stabbed himself in the leg and showed up at work claiming to have just been attacked by three Hispanic males. Siebers, who told cops he was assaulted as he walked toward the Blockbuster in Edgewater, had a deep stab wound in one leg and several other minor cuts on his face and stomach. As investigators began hunting for the assailants, they reviewed surveillance video from outside a Target store where Siebers claimed the attack occurred. The footage, however, showed no such assault. Confronted by cops, Siebers, pictured in the below mug shot, admitted that he had stabbed himself. He told investigators about the skateboarding accident, the resulting ripped pants, and how "he did not want to lose his job so he stabbed himself in the leg," according to an arrest affidavit sworn by Officer Shawna Naumann.

The Blue Sun

Posted by Alex in Pictures, Science & Tech on November 4, 2009 at 1:36 pm


Image: Alan Friedman of Averted Imagination

Alan Friedman, a greeting cards-maker by day and astronomer by night, took this amazing photo of the Sun. APOD explains why it’s blue:

Our Sun may look like all soft and fluffy, but it’s not. Our Sun is an extremely large ball of bubbling hot gas, mostly hydrogen gas. The above picture of our Sun was taken last month in a specific red color of light emitted by hydrogen gas called Hydrogen-alpha and then color inverted to appear blue. In this light, details of the Sun’s chromosphere are particularly visible, highlighting numerous thin tubes of magnetically-confined hot gas known as spicules rising from the Sun like bristles from a shag carpet. Our Sun glows because it is hot, but it is not on fire. Fire is the rapid acquisition of oxygen, and there is very little oxygen on the Sun. The energy source of our Sun is the nuclear fusion of hydrogen into helium deep within its core. No sunspots or large active regions were visible on the Sun this day, although some solar prominences are visible around the edges.

How An American Soldier Is Made: The Story of Ian Fisher

Posted by Alex in Pictures, Weapons & War on November 4, 2009 at 1:35 pm


Photo: Craig F. Walker / The Denver Post

What does it take to create an American Soldier? Denver Post Photojournalist Craig F. Walker tracked Ian Fisher from his high school graduation through basic training, assignment to Colorado’s Fort Carson, and deployment in Iraq:

His decision to join the Army grew out of many things. The opportunity to fight for his country. The desire to add to a family legacy. The need to point his young life in a productive direction. In the spring of 2007 and at the depths of the Iraq war s unpopularity, Ian Fisher graduated from Lakewood s Bear Creek High School and, two weeks later, shipped out to basic training. There, he began the challenging process of becoming an American soldier – and outgrowing the trappings of youth. Like many recruits, he would struggle, learn, make mistakes and rebound. His training prepared him for violent conflict in a foreign land. Nothing prepared him for the war within.

Calf Gets Prosthetic Legs

Posted by Miss Cellania in Animal, Medicine on November 4, 2009 at 12:56 pm

Nancy Dickenson of Ocate, New Mexico and her stepdaughter Martha found an 11-month-old calf on a neighbor’s ranch that was suffering from severe frostbite. The black angus heifer had lost the use of her back legs and hooves. What to do? Obviously, the answer is to give her prosthetic legs!

The Dickensons have rescued dozens of animals and wanted to give Meadow a chance to walk normally again. They located the calf’s owner and bought Meadow, and convinced veterinarians and students at Colorado State University to help her.

Doctors amputated a portion of Meadow’s hind legs in August and fitted her with the prosthetics, a rare procedure done on livestock typically destined for the food supply. Meadow is believed to be the first bovine calf fitted with double prosthetics, Colorado State veterinarian Dr. Robert Callan said. He based his claim on discussions with other veterinarian clinics and schools.

Nancy Dickenson said the family decided to pay what she expects will cost “thousands of dollars” for the procedures because Meadow has become another family pet.

Meadow is no longer in any danger of becoming beef. Link -via Fark

Energy-Harvesting Rocking Chair

Posted by John Farrier in Arts & Crafts, Science & Tech on November 4, 2009 at 12:09 pm


Photo: Design Boom

Rochus Jacob designed and built the Murakami Chair. As the user rocks back and forth during the day, the chair charges a battery that powers the lamp. Jacob writes:

I was looking for opportunities to generate energy through activities we naturally do. The final result is a rocking chair that enables the user to experience production and consumption of electricity in a gentle and rewarding way. An abstract process becomes tangible and eventually cultivates natural awareness. Complexity is covered by simplicity. Advanced nano-dynamo technology which is built in to the skids of the chair and more efficient light sources such as the newly developed OLED generation makes it possible to build a rocking chair with a reading lamp running on electricity generated from the rocking motion. During daylight the energy gets stored in a battery pack. The construction of the flat and bendable organic light emitting diodes allows new form factors such as using the traditional shape of a lamp but instead of having a light bulb the lampshade himself turns out to be the light source. To have a drastic reduction of consumption the big challenge will be to make consuming less feel like getting more.

What Your Taste in Beer Says About You

Posted by John Farrier in Advertising on November 4, 2009 at 9:43 am

The market research firm Mindset Media studied the cultural and economic behaviors of beer drinkers and discerned certain trends among buyers of particular beers. Among the brands studied are Budweiser, Bud Light, Corona, Heineken, and Blue Moon. Beth Snyder Bulik wrote about the study in Ad Age. Here’s what she wrote about Budweiser drinkers:

True to form, Bud drinkers are sensible, grounded and practical. They are the polar opposite of daydreamers and don’t easily get carried away. These beer drinkers also don’t like authority—can anyone say union?—and are emotionally steady people who live in the here and now. However, what may be a bit surprising is that people who prefer Bud can also be very spontaneous and tend not to do much advance planning.

Budweiser drinkers are 42% more likely to drive a truck than the average person, 68% more likely to choose a credit card with flexible payment terms and 42% more likely to use breath-freshening strips every day.

Dog vs. SUV: Which Has Larger Eco-Footprint?

Posted by Alex in Animal, Car & Vehicle on November 4, 2009 at 2:23 am


This guy is destroying Earth!

Which has a larger ecological footprint, a large dog or an SUV? According to Robert and Brenda Vale, Fido has a Hummer of an eco-footprint:

In "Time to Eat the Dog? The Real Guide to Sustainable Living," authors Robert and Brenda Vale argue that resources required to feed a dog — including the amount of land needed to feed the animals that go into its food — give it about twice the eco-footprint of, say, building and fueling a Toyota Land Cruiser. Noting that a cat’s pawprint was roughly equivalent to a Volkswagen Golf’s, "New Scientist" asked an environmentalist at the Stockholm Environment Institute in York, U.K., to independently calculate animals’ environmental impact, and reported that "his figures tallied almost exactly." The study apparently didn’t take into account the emissions of either the SUV or the dogs.

Being Grumpy is Good For You

Posted by Alex in Medicine on November 4, 2009 at 2:21 am

Feeling grumpy? Don’t feel bad – it may actually be good for you:

An Australian psychology expert who has been studying emotions has found being grumpy makes us think more clearly.

In contrast to those annoying happy types, miserable people are better at decision-making and less gullible, his experiments showed.

While cheerfulness fosters creativity, gloominess breeds attentiveness and careful thinking, Professor Joe Forgas told Australian Science Magazine.

13 Examples of Literature in Song

Posted by Johnny Cat in Book & Lit, Music, Neatorama Only on November 4, 2009 at 2:20 am

2791c6971acb76eef9b5f50oa8poe

It’s no real surprise that Wikipedia has a thorough list of these, but it’s interesting to parse through the many, and find a neat collection of songs and albums that were based on, or influenced by books.  Led Zeppelin has a scatological lyric library referencing JRR Tolkien, but let’s see what else is out there.

13. Alan Parson’s Project – The album is called Tales of Mystery and Imagination, and includes interpretations of  Edgar Allen Poe’s best, like “The Raven”, “Dr. Tar and Professor Feather”, and “The Cask of Amontillado.”  Here’s the awesome “Dream Within A Dream” video.  Also by Parsons: “I, Robot” (Isaac Asimov).

12. Rivendell (Rush) – A quiet, thematic representation of the Elf version of a Bed & Breakfast. (Tolkien’s Lord of the Rings, of course.)

11. 2112 (Rush) - Side one* is loosely based on Anthem by Ayn Rand.

10. For Whom the Bell Tolls (Metallica) - Based on the classic by Ernest Hemingway.

metallica.preview

9. The Thing That Should Not Be and The Call of Cthulu (Metallica) - These guys really let good classic fiction influence their songwriting.  We get not one, but two songs in honor of H.P. Lovecraft’s best character.  Also by Metallica: “One”, based on the book Johnny Got His Gun by Dalton Trumbo.

8. The Small Print (Muse) - “clearly alluding to Goethe’s Faust, being sung from the point of view of the Devil to someone selling their soul to him in exchange for, presumably, musical prowess and fame…” source

7. Anthrax Loves Stephen King - As do a lot of bands like Pennywise (It).  But Anthrax named one of their best albums Among the Living after King’s character Randall Flagg in The Stand.  They also penned a song called “Skeleton in the Closet” based on King’s “Apt Pupil”.

The-Adventures-of-Tom-Sawyer-Mark-Twain-unabridged-retail-mp3-compact-disc-Blackstone-Audio-books

6. Tom Sawyer (Rush) - Wow, Rush.  Even “Red Barchetta” is based on a vague book called A Nice Morning Drive by Richard S. Foster.  At least Tom Sawyer is pretty well known both as a song and a book.  Who can resist the urge to sing along when Geddy Lee croons, “The River!”

5. Tales of Brave Ulysses (Cream) - Psychedelically sums up all you need to know about all the ins and outs of Homer’s The Odyssey.  And I quote, “Tiny purple fishes run laughing through your fingers…”  (This was actually a lyric inspired by lyricist Martin Sharp’s travels in Ibiza.)  But the Sirens are there, so that’s cool.

4. The Ghost of Tom Joad (Bruce Springsteen) - Based on The Grapes of Wrath by John Steinbeck.  Henry Fonda and Bruce Springsteen would have had some cool conversations, I bet.

3. White Rabbit (Jefferson Airplane) -Based on Lewis Carroll’s Alice in Wonderland.  Here’s a nice rendition of that song.

YouTube Link

2. Animals (Pink Floyd) - It never actually occurred to me before, but an argument can be made that the Animals album, with it’s corrupt pigs (be they on the wing, or three different ones), dogs and sheep, political overtones…  Yeah, it’s definitely based on George Orwell’s Animal Farm.

1. Iron Maiden (Pretty much every song of theirs, ever) - At least a heavy handful.  These Brit bad boys of metal must have had some scratched up library cards.  Their adaptations include:

  • Seventh Son, by Orson Scott Card (on the 7th Son of a 7th Son album, including all songs)
  • Brave New World (Aldous Huxley)
  • Flight of Icarus (Mythology)
  • The Lord of the Flies (William Golding)
  • The Loneliness of the Long Distance Runner (Alan Sillitoe)
  • Stranger in a Strange Land (Robert A. Heinlen)
  • To Tame a Land (Dune, Frank Herbert)
  • The Trooper (The Charge of the Light Brigade, Alfred Tennyson)
  • Rime of the Ancient Mariner (Samuel Taylor Coleridge)
  • Murders in the Rue Morgue (Edgar Allen Poe)

On second thought, an honorable mention should be made for Led Zeppelin’s “The Battle of Evermore”, as it pretty much describes the Battle of Pellennor Fields in The Return of the King.

The Bald Bear

Posted by Alex in Animal on November 4, 2009 at 1:45 am

Vets are baffled at this strange sight: Dolores, a spectacled bear at the Leipzig Zoo in Germany has gone bald!

It could be due to a genetic defect but the animals don’t seem to be suffering any other afflictions.

The normally fluffy dark brown bears should be now growing a thick fur coat to keep them warm during the winter.

One thing the lack of hair shows up in their huge, lethal claws.

But instead the bears, which once originated from South America, have begun developing nasty rashes and inflammations on their skin where their glossy coats should be.

6-Year-Old Girl with Brain Cancer Hid Love Notes for Her Parents to Find After Her Death

Posted by Alex in Baby & Kids, Medicine on November 4, 2009 at 1:39 am

When 6-year-old Elena Desserich was diagnosed with brain cancer, she began hiding hundreds of little love notes around the house for her parents to find after she was gone. Here’s the story:

Just before her sixth birthday, Elena Desserich (right) was diagnosed with brain cancer and given 135 days to live. She lived 255 days, passing away in 2007. After her death, Elena’s parents, Brooke and Keith, found hundreds of notes from Elena hidden around the house — in between CD cases, between bookshelves, in dresser drawers, in backpacks….

"It just felt like a little hug from her, like she was telling us she was looking over us"

Elena left hundreds of notes like these:


See more of Elena’s notes

Elena’s parents, Brooke and Keith Desserich, have now published these notes in a book called Notes Left Behind to fund a non-profit organization The Cure Starts Now dedicated to fighting pediatric brain cancer.

Ah, this broke my heart, but the story is too touching not to share. Excuse me while I, erhm, dry my eyes. Got dust in ‘em or something.

Top 10 Mad Science-Worthy Chemistry Experiments

Posted by Alex in Neatorama Only, Science & Tech, Video Clips on November 4, 2009 at 12:10 am

Chemistry is a fascinating science, but it's often taught poorly in today's boring schools. Here's how chemistry should be taught: by mad scientists! Here's Neatorama's list of the Top 10 Mad Science-Worthy Chemistry Experiments:

1. Briggs-Rauscher Reaction


[YouTube Clip]

The Briggs-Rauscher reaction is a well known example of oscillating chemical reactions, also known as chemical clocks because the periodicity can be used to tell time. What's going on in the beaker is actually quite a complex set of chemical reactions. Here's how to do it: Link

2. Gummy Bear and Molten Potassium Chlorate

Who'da thunk that Gummy Bear can be so ... violent? Here's what happen if you drop a Gummy Bear (which is mostly sugar), to a tube of molten potassium chlorate:


[YouTube Clip]

3. Diet Coke and Mentos


Mentos in various carbonated liquids. From left to right: carbonated water (Perrier), Classic Coke, Sprite, and Diet Coke. By K. Shimada [Wikipedia]

You've all seen this before. The Diet Coke and Mentos experiment by Fritz Grobe and Stephen Voltz of EepyBird was the stuff of Internet legend back in 2007. But what exactly happens when you drop a Mentos into a solution of Diet Coke?

MythBusters explain:

According to Hyneman (he's the mustachioed MythBuster), it's a process called "nucleation," in which the particular chemistry of the Mentos candy interacts with the chemistry of the carbonated Diet Coke, causing the carbon dioxide gas, or CO2, to suddenly come out of suspension in the liquid and make a break for freedom. [...]

Hyneman says, "There's a cascade that happens with -- it's a little esoteric -- an ion exchange. Basically the Mentos start to dissolve, and it's like tripping a switch. It's not what you would call a chain reaction, because that's something else in chemistry terms, but it's a cascade whereon all of a sudden, all of the CO2 that was contained in the liquid is suddenly not as attracted to the liquid as it was before, because of this slight change in the chemistry that occurs."

Whatever you do, don't eat a mentos then chug a mouthful of diet soda, mmkay?

4. Elephant Toothpaste


[YouTube Clip]

Yes, even elephants need to maintain good dental hygiene, but what kind of toothpaste do they use? Here's a favorite chemistry demo called Elephant Toothpaste (no, elephants don't actually use this as a toothpaste, silly - it's only called that because it looks like the kind and quantity of toothpaste an elephant would use).

This one's easy to do, all you need is dish soap, hydrogen peroxide, and potassium iodide: Link

5. Grape Plasma

What happens if you put a grape and nuke it in a microwave? You get something very cool ... and dangerous at the same time, because it *will* ruin your microwave, release poisonous gases, and you *can* burn down your house - so don't do it, mmkay? Watch:


[YouTube Clip]

What just happened? Here's the explanation, according to The Plasma Universe:

It is relatively easy to generate a plasmoid using a microwave and a medium that will initiate the formation of a plasmoid, this can be caused by the carbon microparticles in the smoke from a naked flame or match, which ignites and moves about as plasmoids, and some biological cells are known to produce plasma under microwave conditions, such as grapes (electrons try to move through highly resistive grape-skin, and plasmoids may form) This is due to the fact that microwaves, being high frequency electromagnetic radiation in the GHz range, are capable of exciting electrodeless gas discharges in air, similar to the process used in Sulfur lamps.

Got that?

6. Burning Salts

Quick: what color is fire? Orangey red? Obviously you haven't seen alcohol, barium chloride, boron, strontium, calcium, lithium, sodium, copper, and potassium salts set aflame ...


[YouTube Clip]

7. Magnesium in Dry Ice

You've probably heard that fire needs oxygen to burn (indeed, the principle behind CO2 fire extinguisher is to use the heavier carbon dioxide to displace the oxygen needed by the flame).

But does a fire really need oxygen? Not burning magnesium! It'll burn even when encased in dry ice (solid CO2). Note: magnesium shavings are used - not powder, which will explode if you try to set it on fire.


[YouTube Clip]

8. Ferrofluid

Ferrofluid, a colloidal mixture of nanoscale magnetic particles in a solvent, reacts to magnetic field in an awesomely bizarre way. Sachiko Kodama uses ferrofluid to create dynamic sculptures called Morpho Towers:


[YouTube Clip]

9. Mercury Beating Heart


[YouTube Clip]
