10 Most Extreme Subtances

Extreme has (luckily) lost most of its buzz-word status. It’s mostly back to meaning things on the fringe, way out near the edges, where they blow our minds with their extremeness, rather than simply having 3 times the corn syrup and colors nature never intended.

That being said, for every type of substance, there is a “most extreme” version. Sure, we’ve all heard stories about magnets strong enough to cripple kids from the inside, and acids that will eat through your hands in seconds, but did you know there are even more “extreme” versions of those? Here are the top 10 most “out there” substances I could find.



10. The Darkest Substance Known to Man

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. Scientists are really excited about the potential applications of the substance; since virtually no light is “wasted”, it would be used to improve optical tools like telescopes, and even be used to make nearly 100% efficient solar collectors.



9. The Most Flammable Substance

A lot of things burn with astounding intensity; Styrofoam, napalm, marshmallows are just the beginning. But what if there was a material that could set sand on fire? Okay, so clearly that was a loaded question, but it was a necessary set-up. Chlorine triflouride has the dubious honor of being terrifyingly flammable, to the point that history’s evil boy-scouts, the Nazis, deemed it too dangerous to work with. When people who consider genocide their life’s goal don’t want to use something because it is too deadly, it bears treating it with some caution. There is a story that a ton of the stuff was spilled once and caught fire, and it burned through 12 inches of concrete and another meter of sand and gravel before going out. I hate to say it, but in this case, the Nazi’s were right.



8. The Most Toxic Poison

Quick, what’s the last thing you would want to inject into your face? Aside from something that burns through concrete, and maybe the world’s worst acid (coming soon), I would think “The world’s deadliest poison” would be in the top 3 with them. Not so, though, in the medical community; you’ve all heard of Botox, no doubt, and “deadliest poison” is it’s main claim to fame. Botox uses botulinum toxin, produced by the bacteria Clostridium botulinum, and it is so deadly, an amount equal to a grain of salt is enough to kill a 200 lb man. In fact, they even suggest that it would only take 4kg, properly dispersed, to kill every last person on earth. Maybe those crows feet around your eyes would be better treated with an angry rattlesnake….



7. The Hottest Substance Ever

There are few things known to man hotter than the interior of a freshly microwaved Hot Pocket, but this stuff manages to break even that record. Created by smashing gold atoms together at nearly the speed of light, it’s called a quark-gluon soup, and it reaches a balmy 4 trillion degrees Celsius, a mere 250,000 times hotter than the inside of the sun. The amount of energy released in the collision was sufficient to melt protons and neutrons, which in itself could be featured on a list of things you never even knew were possible. Scientists think this substance could give us an idea of what the birth of our universe was like, so it’s good to see they aren’t just creating tiny supernovas for the fun of it. However, the really good news is that the soup was only a trillionth of a centimeter across, and only lasted for a trillionth of a trillionth of a second.



6. Most Acidic Acid

Acid is scary stuff; they gave one of the scariest movie monsters ever acid blood to make it scarier than just a simple killing machine (the Alien), so it’s pretty ingrained in our psyche that getting dissolved is bad. If the Aliens had been filled with fluoroantimonic acid, they not only would have probably fallen through the floor until they hit dirt, the vapors given off by their dying bodies would have killed everyone around them. It is 21019 times more powerful than sulphuric acid, and can even eat through glass. And it explodes when exposed to water. And when it is reacting, it gives off poisonous fumes that can kill everyone in a room. Maybe we should move on from this one…



5. The Most Explosive Expolosive

This particular honor is actually currently shared between two compounds; HMX and Heptanitrocubane. Heptanitrocubane mostly exists in labs, and is similar to HMX, but has a denser crystal structure, giving it greater destructive potential. HMX, on the other hand, exists in quantities large enough to be physically threatening. It is used in solid rocket fuel, shaped charges, and even nuclear weapon detonators. That last one is the scariest, because despite how easy movies make it look, starting the fission/fusion reaction that makes bright glowing radioactive mushroom clouds is not an easy ball to get rolling, but HMX is up to the task.



4. The Most Radioactive Substance

Speaking of radiation, it’s worth noting that the glowing green rods of “plutonium” on the Simpsons are completely fictional. Just because something is radioactive does not mean it glows. I mention that because Polonium-210 is so radioactive, it glows blue. A former soviet spy, Alexander Litvinenko, was duped into consuming some without his knowledge, and he died of cancer shortly thereafter. This is not that kind of thing you ever want to mess with; the glow is caused by the air around it being excited by the radiation, and it can actually heat objects nearby. If the fact that something highly radioactive gives off heat, keep in mind that when we usually think “radiation”, we are thinking of things like a nuclear reactor or explosion, where an actual fission reaction is happening. This is just your run of the mill loss of ionized particles, not a runaway splitting of atoms.



3. The Hardest Substance

If you thought the hardest substance on earth was diamond, that was a good, if inaccurate guess. It is technically an aggregated diamond nanorod. It is actually a collection of nano-scale diamonds, and it is the least compressible, hardest substance known to man. They aren’t naturally occurring, which is actually kind of cool, since it implies we could one day coat our cars in this stuff and just walk it off when we collide with a train (not really). It was developed in Germany in 2005 and will likely be used in the same capacity as industrial diamond, except will be more wear-resistant than regular diamonds. That’s harder than algebra.



2. The Most Magnetic Substance

If Magneto was a small black lump, that would be him. The substance, developed in 2010 out of iron and nitrogen, is 18% more magnetic than the previous record holder, and is so powerful, it has forced scientists to revisit how magnetism works. The man who discovered the substance has taken great pains to ensure that his work can be reproduced by other scientists, because a similar compound was reported developed in Japan back in 1996, but other physicists could not replicate it, so it was never officially accepted. No word on whether Japanese physicists have to commit Sepuku under these circumstances. If it can be reproduced, it could spell a new age of efficient electronics and magnetic engines, maybe even powered by number 10.



1. The Most Super Superfluid

Superfluidity is a state of matter (like solid or gaseous) that occurs at extremely low temperatures, has high thermal conductivity (every ounce of it is always exactly the same temperature), and no viscosity. Helium 2 is the “most” example of this. A cup of He2 will spontaneously flow up and out of a container, as if it just decided to leave. It also seeps right through otherwise solid materials because its complete lack of friction allows it to flow through otherwise invisible holes that would not allow regular helium (or water for that matter) to flow through. He2 did not wind up at number 1 just because of its ability to act like it has a mind of its own, though, it is also the most efficient thermal conductor on earth; several hundred times that of copper. Heat moves so fast through Helium 2 that it moves in waves, like sound (and is fact known as “second sound”), rather than dispersion, where it simply transfers from one molecule to another. Incidentally, the forces governing He2’s ability to crawl walls is called “third sound”. You can’t get much more extreme than a substance that required the definitions of 2 new types of sound.

Blue Pond in Hokkaido

The Blue Pond is located in the left bank of the River Bieigawa, southeast of the town of Biei in Hokkaido, Japan, about 2.5 km northwest from the Platinum hot springs at the foot of Mt. Tokachi. The pond gets its name from the unnaturally bright blue hue of its water. With tree stumps protruding from the surface of the water, not unlike Lake Kaindy, the Blue Pond has an ethereal and enchanting appearance.

The Blue Pond wasn’t there from very long. It’s an artificial pond created when a dam was erected to protect the region from mudflows that might occur from the nearby volcano on Mt. Tokachi. In the wake of the eruption on December 1988, the Hokkaido Regional Development Bureau decided to construct a dam upstream on the Bieigawa river to prevent mudflow. Water blocked by the dam now accumulates in a depression in the forest creating the Blue Pond.

The blue color of the pond has not been fully explained but is attributed to the presence of aluminum hydroxide in the water that reflects the shorter wavelength blue light the same way the earth’s atmosphere does. The color of the pond also changes depending on what angle you look at it from and even at different times of the day. Although the water appears blue when viewed from the land, the color is not found in the water itself.

The picturesque town of Biei has been a popular tourist destination for years, but the Blue Pond became a global attraction only recently after Apple included an image of the aquamarine pond in the recently released OS X Mountain Lion

Kelley Island's Glacial Grooves

Many of the geological features on the surface of this planet has been shaped by ancient glaciers. These gigantic sheets of ice of immense weight moving across the earth have carved gorges, grinded rocks into fine gravel, raised sea level and left boulders at unexpected places when they melted away. But it’s another thing to hear a geologist say “the sand in this desert was created by glaciers” or “this gorge was carved by glaciers” and quite another to actually see scratches and grooves on the bedrock left behind by glaciers as it dragged over the surface. These abrasions are called Glacial Grooves and the most outstanding example of this feature can be found at Kelleys Island, in Ohio, in the United States.

Glacial grooves, also called glacial striations, were first recognized as the result of a moving glacier in the late 1700s by Swiss alpinists. They were also one of the first to realise that if they were visible today, then the glaciers must also be receding.



Ice, however, is not hard enough to cut through a rock. It’s the rock fragments and sand grains embedded underneath the glacier that provide the abrasive power to cut trough-like glacial grooves. The finer sediments in the base of the moving glacier further scour and polish the bedrock surface, forming a glacial pavement.

The glacial grooves on the north side of Kelley’s Island are the largest easily accessible such grooves in the world. They were scoured into solid limestone bedrock about 18,000 years ago by the great ice sheet which covered part of North America. This impressive groove is 400-feet long, 35-feet wide, and up to 10-feet deep. The ice which created these grooves were probably hundreds of feet thick and flowed from the north in what is now the Lake Erie basin. The grooves were under several feet of soil before they were dug out in the 1970s.

At one time Kelley's Island had a much larger glacial groove area with grooves over 2,000 feet in length. It was called the “Great Grooves”. Unfortunately, active quarrying in the area destroyed most of the grooves. The remaining grooves are now protected and fenced in, although open for public. The old rock quarry is still visible behind the Glacial Grooves State Memorial.

Monemvasia

Monemvasia is a Gibraltar-like rocky island off the east coast of the Peloponnese, in Greece, and linked to the mainland by a short causeway. The island is about 300 meters wide and a kilometer long, and rises in a plateau, a hundred metres above sea level. On the slope of this plateau, on the seaward side and hidden from the mainland, lies a small town. This remarkably romantic walled town, nestled under the shadow of the towering rock is a living museum of Byzantine, Ottoman, and Venetian history dating back to the 13th century.

Monemvasia was settled in the 6th century by the inhabitants of ancient Laconia seeking refuge from the Slavic invaders who dominated much of Greece between 500 to 700 AD. The rocky island had been separated from the mainland by an earthquake in 375 AD. Over the next several centuries, Monemvasia changed hands again and again, back and forth, between the Venetians and the Turks, until it was liberated during the Greek War of Independence in the early 19th century.



The name Monemvasia is derived from two Greek words, mone and emvasia, meaning "single entrance" and refers to the narrow causeway which is the only way to enter the town.

The island was initially settled on the top of the plateau, which is now referred to as the “Upper Town”. Gradually the settlement spread down the hill, and thanks to its uniquely well-defended position, developed into a powerful town. In the declining days of the Byzantium Empire, Monemvasia became its main city and one of the great commercial centers of the Byzantium world and a major trading port, with a population of 40,000. By the 18th century, Monemvasia went into decline until it was re-discovered by tourists in the 1970’s.

Slowly, the town is resurging in importance – this time as tourist destination with an increasing numbers of tourists visiting the region during the summer. The medieval buildings have been restored, and many of them converted to hotels, and there are plenty of places to eat.

Floating Tree Trunks on Spirit Lake

The May 18, 1980 eruption of Mount St. Helens, a volcano located in state of Washington, was one of the most destructive events in the history of the United States. In just a matter of hours, the north face of the volcano collapsed creating a huge landslide - the largest debris avalanche in recorded history – that moved swiftly towards the surrounding lakes and the North Fork Toutle River valley leaving a trail of destruction 27 km long. Located only about 5 miles north-northeast of the volcanic crater, Spirit Lake received the full impact of the lateral blast.

An estimated 1 million trees were blown away from the surrounding hillside by a super-heated wall of volcanic gas and searing ash and rock, and these along with other rubble were deposited on Spirit Lake. The debris avalanche temporarily displaced much of the lake from its bed sending 600-foot-high waves crashing into a ridge north of the lake. As the water moved back into its basin, it pulled with it thousands of more trees into the lake. About 350,000 acre-feet of pyrolized trees were deposited into Spirit Lake and these shattered trees formed a floating log raft on the lake surface that is present to this day, more than three decades after the event.

Prior to the eruption, Spirit Lake was a popular and picturesque body of water and was well known to many people as a vacation spot. There were six camps on the shore and a number of lodges catering to visitors.

Today, Sprit Lake is a wasteland choked with thousands of logs and volcanic debris. Huge quantities of debris decreased the lake volume by approximately 46,000 acre-feet, and its depth by 80 feet. Lahar and pyroclastic flow deposits from the eruption blocked its natural pre-eruption outlet to the North Fork Toutle River valley at its outlet, raising the surface elevation of the lake by 200 feet.

When scientists saw the mass destruction, they realised that Sprit Lake provided them with a rare opportunity to study microbial and chemical transformations and the biological restoration of a lake severely impacted by a major volcanic disturbance. To ensure protection of Spirit Lake and other recovering ecosystems inside the volcano's 220-square-mile blast area, the Mount St. Helens National Volcanic Monument was created in 1982. Fishing and other recreational activities potentially disruptive to Spirit Lake's recovery are prohibited. This is one of the primary reasons why no attempts were made to recover the logs and other forest debris floating in the lake.
