Drawing with Fire

Posted by John Farrier in Art, Art & Design on February 4, 2012 at 6:52 pm

Steven Spazuk draws with fire by holding a candle up to pieces of canvas, then adjusting the soot with brushes, knives, and his fingers to create images. I really like his impressionistic works, like the one above. But from a technical perspective, his massive composite portraits consisting of hundreds of smaller pieces demonstrate the magnitude of his skills. Watch a video at the link showing how Spazuk does it.

6 Infamous Arsonists and How They Got Caught

Posted by Miss Cellania in Crime & Law on January 6, 2012 at 3:47 pm

An investigation of the dozens of arson fires in Los Angeles last weekend led to the arrest of 24-year-old German national Harry Burkhart. The case inspired Meghan Holohan to look up famous arson cases and the men who set those fires. Take the case of John “Pillow Pyro” Orr, who set around 2,000 fires that killed four people.

During an arson investigators conference in Bakersfield, Calif., in January 1987, several suspicious fires broke out. At one of the fires, investigators found a single fingerprint on a piece of notebook paper. Two years later, during another fire investigators conference in Pacific Grove, an outbreak of small fires occurred. Bakersfield’s arson investigator compared the participants at both conferences and found 10 people attended both. By 1991, the investigators formed the Pillow Pyro task force and published a profile, noting the suspect was most likely an arson investigator from the greater Los Angeles area. The fingerprint found at the first conference was compared to those of the 10 attendees of both conferences; it matched Orr’s fingerprint. When he was arrested in November 1991, police found cigarettes, rubber bands, and binoculars.

A book Orr had written earlier about a fireman who was an arsonist did not help his defense. Read the story of Orr and five other arsonists at mental_floss. Link

Ape Can Start Fire to Cook a Meal

Posted by Alex in Animals & Pets on January 1, 2012 at 2:48 pm

Kanzi, the bonobo that surprised researchers with its linguistic skills (he had learned lexigrams naturally, simply by watching its mother), added a new skillset that will be handy when the apes rise up to take over the world: he can start a fire to cook meals!

Dr Savage-Rumbaugh, of the Great Ape Trust, in Des Moines, Iowa, adds: ‘Kanzi makes fire because he wants to. He used to watch the film Quest For Fire when he was very young which was about early man struggling to control fire. He watched it spellbound over and over hundreds of times.’

He was also fascinated by the camp fires his keepers made to cook food. And he was encouraged to interact with humans and copy them. At the age of five, he was making small piles of bone dry sticks.

20 Things You Didn’t Know About… Fire

Posted by Miss Cellania in Science & Tech on October 9, 2011 at 4:45 pm

In the October issue of Discover magazine, LeeAundra Keany tells us that a bonfire is “basically a tree running in reverse,” and other interesting facts.

1  Fire is an event, not a thing. Heating wood or other fuel releases volatile vapors that can rapidly combust with oxygen in the air; the resulting incandescent bloom of gas further heats the fuel, releasing more vapors and perpetuating the cycle.

2  Most of the fuels we use derive their energy from trapped solar rays. In photosynthesis, sunlight and heat make chemical energy (in the form of wood or fossil fuel); fire uses chemical energy to produce light and heat.

3  So a bonfire is basically a tree running in reverse.

4  Assuming stable fuel, heat, and oxygen levels, a typical house fire will double in size every minute.

How Cooked Food Made Us Human

Posted by Miss Cellania in Food & Drink, Mentalfloss on September 30, 2011 at 5:13 am

Want to know how a bunch of brawny apes evolved into brainy humans? It all comes down to a pair of tongs and a flame.

People and animals eat basically the same food; the only difference is that we cook our meals. But does the ability to flame-broil a burger and burn a meal really make us that special? According to Harvard anthropology professor Richard Wrangham, it does.

Armed with mounting evidence, Wrangham believes that fire-kissed foods are what separated man from beast, allowing our ancestors to grow bigger brains and evolve into the intelligent creatures we are today.

THE MISSING LINK

The story starts roughly 2 million years ago in the age of the habiline -the so-called “missing link” between humans and apes. Habilines walked upright, made primitive stone tools, and had brains the size of oranges (roughly half the size of our brains today). Like chimpanzees, they subsisted mainly on fruits and veggies, with the occasional bit of raw meat on the side. They had strong teeth to chew all that plant matter, and big guts to process all that fibrous material. For them, digestion took an extremely long time. In fact, it’s believed that their bodies were constantly engaged in processing food. (Even today, chimpanzees spend more than six hours a day just chewing.)

So, how did Homo habilis evolve into Homo erectus? The dominant theory since the 1950s has been that meat-eating was responsible for the shift because it required habilines to gradually develop human intelligence. There’s something to the idea: To hunt game, our apelike ancestors had to reply on more than just physical prowess; they had to be clever and cooperate. The better they got at hunting, the smarter they became.

But the “meat made humans” hypothesis rankled biologist Richard Wrangham. In his 2009 book Catching Fire, Wrangham argues that meat-eating alone cannot account for the tremendous physical changes that occurred in the evolution of humans. Instead, he believes that man’s discovery of fire -and more importantly, cooking- did the heavy lifting.


(Image credit: Banksy work, photo by Flickr user Lord Jim)

For decades, many scientists dismissed cooking as a pleasant byproduct of civilization, a symbol of man’s dominion over nature. But Wrangham builds the case that cooking was crucial to human evolution because it made digestion so much more efficient, increasing the amount of energy our bodies derived from what we ate. As a result, humans became better able to think, hunt, sing, dance, paint on walls, and invent new tools. Ultimately, the top chefs were more likely to survive, reproduce, and pass along cooking techniques to their offspring, along with the physical evolutionary changes that come with them -namely, bigger brains.

The idea that cooked food offers more energy than uncooked food doesn’t immediately make sense. After all, recent studies show that cooking can leach food of its calories and nutrients. To understand the answers, we need to look inside -literally.

‘Mystery tree’ Survives Wildfire -Again

Posted by Miss Cellania in Environment on August 11, 2011 at 10:08 am

A 20-foot juniper tree near Sunset Point, Arizona survived a wildfire last week that consumed everything around it. It’s not the first time, either. In fact, the tree is a famous survivor.

Every year it’s decorated for Christmas and Independence Day. Right now, it’s covered with several American flags and yellow ribbons. It also has its own water system set up underneath, with several large drums and a pipe to feed it water.

That’s where the tree gets its name — the mystery tree. A mystery person or people decorate it every year, but it’s also a mystery because it manages to have survived several wildfires over the years.

“It’s survived wildfire after wildfire” says ADOT engineer Greg Gentsch. “We’re just happy it’s still here.”

What are the most extreme substances in the world? No, not Mountain Dew;  this list compiles and gives the details on the hottest, most flammable and most acidic substances known to man. One of which can melt through twelve layers of concrete.

What do you get when you stack carbon nanotubes on their ends and sandwich them together? A material that absorbs 99.9% of the light that touches it. The microscopic surface of the material is rough and uneven, which breaks up the light and makes it a poor reflector. Then add to that carbon nanotubes act as superconductors in certain arrangements, which makes them excellent light absorbers, and you have a perfect storm of black.

Dog Hides in Bathtub to Survive Fire

Posted by Miss Cellania in Animals & Pets on May 2, 2011 at 7:39 am

A home in Greenville County, South Carolina burned for hours as firefighters battled the blaze. The family was away from home, but Mia the one-year-old Belgian Malinois was inside. The dog saved herself by hiding in a bathtub in the basement!

Mia’s owner, Chris Brumby, was amazed at how the dog survived, but said he knew she was smart.

“She acts like a human for most things,” Brumby said. “And that kind of showed it. She knew where to go and hide.”

He said Mia was able to get to a bathtub on the lowest level of the house, where she waited as firefighters doused the home with water. As the water ran down into the basement, it filled the bathtub and soaked Mia, keeping her safe from flames, Brock said.

Brumby said the dog has learned how to open doors throughout the house, and that she had to open four doors to get to the bathtub where she was found.

Six hours after firefighters arrived, they found Mia, wet and sooty, but well. The cause of the fire has is not yet determined. Link -via Arbroath

100 Years Later, the Last Victims are Identified

Posted by Miss Cellania in History on February 23, 2011 at 7:19 am

The Triangle Shirtwaist Factory Fire killed 146 people on March 25th, 1911 when sweatshop workers could not escape the New York City building. The disaster led to safer building codes and worker’s rights laws. However, only 140 of the victims were identified, and that list was only completed by 2003. That left six people buried without markers who were mysteries for a hundred years.

Now those six have been identified, largely through the persistence of a researcher, Michael Hirsch, who became obsessed with learning all he could about the victims after he discovered that one of those killed, Lizzie Adler, a 24-year-old greenhorn from Romania, had lived on his block in the East Village.

And so, for the first time, at the centennial commemoration of the fire on March 25 outside the building in Greenwich Village where the Triangle Waist Company occupied the eighth, ninth and 10th floors, the names of all 146 dead will finally be read.

The New York Times has the story of how the last six were finally named. Link -via Boing Boing

Why Chicago Should be Called Phoenix

Posted by Miss Cellania in Architecture, Mentalfloss on January 27, 2011 at 5:03 am

This is the heroic tale of skyscrapers rising from the ashes of the Great Chicago Fire, and how they inspired changes in cities across the world.

Chicago grew up fast. In 1840, it was a quiet settlement of 4,500 people. Three decades later, it had grown to a vibrant metropolis of 300,000. Unfortunately, the city planners didn’t take much stock of the materials they were using. From the planks of the sidewalks to the shingles on the roofs, the new city was built almost entirely of wood. And in the autumn of 1871, all of that came to a head.

On October 8, during a particularly dry and windy spell, the wood and weather combined to make combustion history. That night, the Great Chicago Fire broke out in a DeKoven Street barn. (The O’Leary family owned it, but their cow had nothing to do with the fire.) The flames advanced quickly, engulfing nearby lumberyards and the city’s downtown, and they burned for 36 hours straight. In the end, 18,000 structures were destroyed, as many as 300 people were killed, and nearly one-third of the population was left homeless.

Yet, the enduring legacy of the Great Chicago Fire is not its destruction, but the amazing rebirth that took place after it.

The rebuilding of Chicago began with Joseph Medill, managing editor and publisher of the Chicago Tribune, who personified the city’s indomitable spirit. Even though the blaze had partially leveled his newspaper’s headquarters, Medill cranked out a special edition two days later, affirming the city’s resolve with an editorial stating, “Cheer up … Chicago Shall Rise Again.” It was more than empty encouragement. One month later, Medill was elected mayor on the city’s “Fireproof” ticket. He immediately ushered in safety reforms that set the stage for rapid development and a new wave of construction.

Within 10 years, the population of Chicago had nearly doubled. Soon, there was no more land to build on, and overcrowding was setting in. But in 1883, architect William Le Baron Jenney came up with a novel solution. He designed the innovative, 10-story Home Insurance Building -widely considered to be the world’s first skyscraper. The Home Insurance Building had the steadiness of a cathedral, but at a third of the normal weight. Jenney’s genius was in using a light steel frame covered in hollow terra cotta tiles to prevent the spread of fire. His skyscraper inspired architects to think vertically and gave rise not just to Chicago’s skyline, but also to new skylines across the globe.

CITY MEETS WORLD

By 1890, less than two decades after the Great Fire, more than 1 million people were living in Chicago. It surpassed Philadelphia in population, and became America’s “second city”, next only to New York. Despite its size, many saw Chicago as a glorified hick town. To change that perception, Chicago competed with New York to host the world’s Columbian Exposition, a fair to commemorate the 400th anniversary of Columbus’ arrival in America. At the time, World’s Fairs were serious business. They had the power to thrust a host city into the global spotlight and bring in enormous revenue and prestige.

While New York had financial titans like J.P. Morgan and William Waldorf Astor bidding in its corner, Chicago had something more compelling -a collective sense of purpose. Department store mogul Marshall Field, who’d lost his original building in the blaze, and industrialist Cyrus McCormick, who’d also lost his factory, pledged a combined $15 million to underwrite the fair. Then an even more surprising thing happened: The taxpayers voted for a referendum pledging an additional $5 million. To them, the World’s Fair wasn’t just a celebration; it was a chance at rebirth.

In the end, Congress decided that Chicago’s bid was stronger than New York’s, and the city went on to host one of the most successful World’s Fairs in history. The 1893 event introduced the world to ragtime music, shredded wheat, hamburgers, postcards, neon lights, and the Ferris wheel. It also influenced architecture for decades to come. The fairground’s classical buildings inspired the nationwide City Beautiful movement, which led to the creation of the National Mall in Washington, DC, and the fair’s layout inspired modern amusement parks, such as Disneyland. The buildings even sparked the imagination of writer L. Frank Baum, who created the Emerald City in their image in his book The Wonderful Wizard of Oz.

On October 9, 1893, on the 22th anniversary of the Great Fire, 716,881 people visited the World’s Fair in one day, shattering all previous Fair attendance records. In just 22 years, Chicago had risen from a pile of rubble to the height of civilization -and the world was there to celebrate.

Escaping Cat Saves Burning House

Posted by Miss Cellania in Animals & Pets on December 15, 2010 at 7:27 am

A 3-year-old cat named Pepper used a trick worthy of Houdini to escape from a burning kitchen in Stoke Gabriel, South Devon, England. Frightened by an exploding microwave, he leapt to a window and nudged the catch open with his nose. Neighbors noticed smoke billowing from the open window and alerted the fire department. Homeowners Phil and Sharon White are grateful the fire was contained.

Phil said: “There is some damage but nothing compared to what it could have been.”

Phil’s wife Sharon added that Pepper is a law unto himself and has a fiery streak. “But all is forgiven now, ” she said.

She said that neighbours also deserve credit.

Sharon said: “We are thankful that they did not just dismiss it as a bonfire. They rallied around and even directed the fire service here through the narrow lanes.”

Pepper is still a bit spooked by his ordeal. “But he is still managing to eat plenty of food,” said Sharon.

In Which I Set Myself On Fire

Posted by Miss Cellania in Science & Tech on October 22, 2010 at 9:49 am

Theodore Gray (featured previously at Neatorama) teaches us how stunt men can go around in flames. By  setting himself on fire. On video.

There are a few perks to my job as a mad scientist, and one of them, as I recently learned, is being able to tell my colleagues that I can’t attend their terribly important meeting because I’m going to set my hand on fire.

In the movies, people on fire stumble out of burning buildings all the time. If you look closely, however, you’ll notice that they are almost always fully dressed, and that they tend to keep moving. These are two important factors that make the stunt much easier.

San Bruno Neighborhood Flattened by Gas Explosion

Posted by Alex in Everything Else on September 10, 2010 at 10:26 am

A massive explosion leveled a neighborhood in San Bruno (a suburb close to San Francisco), California, yesterday night:

After the initial blast, flames reached as high as 100 feet as the fire fueled itself on burning homes, leaving some in total ruins and reducing parked automobiles to burned out shells. At least 120 homes also suffered serious damage.

Witnesses heard the explosion miles away and said it shot a fireball more than 1,000 feet in the air, sending frightened residents fleeing for safety and rushing to get belongings out of burning homes.

"I thought a 747 had landed on us," Barringer told the Times. "It shook our station right to its foundation."

What could’ve caused such an explosion? A ruptured 30-inch steel gas pipeline is suspected. Link (Photo: KNTV)

I used to live near San Bruno and a cousin of mine lives there (she’s okay), so that sort of hit close to home. But have you ever thought about the ground under your house simply exploding?

Fire Tornado

Posted by John Farrier in Video Clips on August 25, 2010 at 1:00 pm

It’s a rare weather event, but a fire tornado was recently caught on camera in a drought-stricken region of Brazil. The tornado started fires in nearby fields, which were contained overnight.

The vortex of fire resulted from months of drought in the region, combined with brush fires and strong, dry winds.

Though a rare phenomenon, the formation of a fire tornado, or fire whirl, is quite simple.

When there is a warm updraft of air and convergence of fire, say from a wildfire, a vortex of flame can occur. As the heated air from the fire rises, strong air currents cause flame to spin, shaping it into a tornado.

At the link, you can read about how to make your own fire tornado at home.

Spontaneous Human Combustion

Posted by Queuebot in Paranormal on August 9, 2010 at 5:56 am

There have been about 200 reported cases of spontaneous human combustion reported in history, in which a person was killed by a fire that could not be explained otherwise. What happened? And is there a scientific explanation for these cases?

The earliest case of SHC that we know of today comes from a Danish anatomist named Thomas Bartholin who in 1663 described an occurrence in Paris where a woman was burnt completely to ashes in her sleep while the straw mattress upon which she was laying remained unmarred by the flames that had consumed her. Since the reporting of this case of spontaneous human combustion to the whole of the European community, many others have been recorded in history. Yet, they tend to have a similar pattern in the resulting accounts. The victim is generally found almost completely consumed by a then died out fire in his or her home or place of residence.

Fire 101

Posted by Miss Cellania in Bathroom Reader, Science & Tech on May 3, 2010 at 3:31 am

The following is an article from Uncle John’s Fast-Acting Long-Lasting Bathroom Reader.

Burning question: Did you ever wonder how fire works? We did. Here’s what we found out.

HOT TOPIC

The scientific definition of fire is “a rapid, persistent chemical reaction that releases heat and light, especially the exothermic combination of a combustible substance with oxygen.” That chemical reaction is called oxidation, which happens when oxygen atoms in the atmosphere combine with atoms “borrowed” from other elements, in this case, from fuel. (Another form of oxidation: rust- it;s just a lot slower.) For fire to occur, three ingredients must be present:

*An oxidizing agent. Can come from a pure oxygen source (like a welding tank) or, more commonly, the air. All that’s needed is an atmosphere of at least 16 percent oxygen; normal air is about 21 percent.

*Fuel. Can be anything from a solid (wood, plastic, or wax), to a liquid (gasoline or alcohol), or a gas (propane).

*A heat or ignition source. Could be lightning, friction (as when striking a match), focused light, or a chemical reaction.

YOU’RE FIRED

For oxidation to take place, the fuel must be heated to a certain temperature, known as the ignition temperature. It’s different for different substances: paper’s ignition temperature, for example, is 451°F. When a fuel reaches it’s ignition temperature, a chemical reaction occurs that begins to decompose it into flammable gases known as volatiles. Some solids, like wood, go directly from solid to gas, while others, like wax, go from solid to liquid and then to gas. This depends on the chemical makeup of the fuel. In either case, the volatiles then violently interact with the oxygen in the atmosphere-that’s called combustion.

Using a candle as an example, when you apply a burning match (the ignition source) to the wax on the wick (the fuel), the wax will heat to a certain temperature (the ignition temperature). It will begin to evaporate and release gases (the volatiles), which then react with the oxygen in the air (combustion). Result: fire.

The heat from the fire will then cause the wax to keep melting and moving back down the wick, evaporating, igniting, and burning away. Because the fire then produces its own heat-a necessary ingredient-it’s called a persistent chemical reaction.

EXTINGUISHED

You already know how to put out a candle-but do you know why it goes out? When you blow out a candle, the wax has cooled below its ignition temperature. If it didn’t go out, you didn’t lower the temperature enough-or for long enough. Try pressing the wick between your thumb and finger. The fire will go out because you removed the fuel source by stopping the wax from climbing the wick. Or put a glass over the candle, taking away the oxygen.

With larger fires, it’s usually difficult to take away the fuel, so fire extinguishers work by eliminating either the oxygen, the heat, or both. Water extinguishers work by cooling the fuel; dry powder extinguishers work by smothering the fire, thereby taking away the oxygen; foam extinguishers both smother and cool the fuel; and carbon dioxide extinguishers displace the oxygen in the air while simultaneously cooling it.

MORE FACTS

*Spontaneous combustion occurs when a fuel reaches its ignition temperature without the aid of an outside ignition source.This can happen because some substances naturally react with oxygen in the air, but most often it’s from spontaneous heating, a slow buildup of heat. A cause of many house fires is the spontaneous heating of oily rags. If there is insufficient ventilation-like in the back of a garage-the heat can build up enough for fire to occur.

*Hot fact: You can’t have fire without oxygen, right? Wrong. All that’s necessary is an oxidizing agent, meaning an element that easily takes electrons from other atoms. Oxygen is the most common agent, which is why the reaction is called “oxidation”. Fluorine, however, is the strongest known oxidizer-much stronger than oxygen. Used in the production of atomic bombs and rocket fuel, fluorine can cause substances like steel or glass to instantly burst into flame. And those flames are virtually impossible to put out.

Why You Should Check If There’s a Recall On Your Car

Neatoramanaut Zavatone, spell checker extraordinaire and all-round good guy wrote me about his recent misadventure involving his car, electrical short, fire, and halon fire extinguisher:

Today, I had the pleasure of venturing back, driving from building to building, taking care of this and that and finally was ready to sit down and get to work with one of my coworkers when a frightened friend of mine ran into our cube and hurriedly stated "black Audi A6 out front?"

Now, I should stop right there, leaving you to guess at all my potential replies, but that would be mean and since it would be mean to be mean after a Monday like I just had, I just won’t do that.

Simply, calmly and with refined grace I replied, "yes?" After which I kindly tilted my ear to hear his response which was, "It’s on FIRE."

Chaos rapidly ensued involving lots of running and glorious clouds of halon*.

Suffice it to say, that my car (while innocuously parked in the OFF position) decided that it no longer approved of its left headlight assembly and proceeded, with sole intent, to burn it off the face of this planet. While this determined vehicle was partially successful, the two of us chaotic running people had to take it upon ourselves to ruin its fun with ample amounts of halon while the rest of the office stood way too close behind us, obviously cheering our efforts or chanting for our demise.

While we did win (I think), this inconvenience certainly dampened my goal of uneventful productivity for the day, but I did learn one thing. That thing is to remember to check if the model of car you drive has any recalls issued by the factory for reasons of "electrical system will likely catch on fire while you are trying to work."

Check your car to see if there are any pending recalls on it. Please.

Thanks Zavatone!

Note by Alex: *That’s not halon, which has fallen out of favor because of cost and environmental concern (the bromine in halon depletes ozone layer). It is no longer produced in the United States as of 1993. Halon doesn’t leave residue. Zavatone probably used a regular dry chemical fire extinguisher. Still, his point remains valid.

The National Highway Traffic Safety Administration has a webpage where you can check if there’s a recall on your car.
