Mysterious Silly Putty Devours Innocent Magnets

If you're old enough to remember the movie The Blob, starring a gelatinous, oozing menace that gooped its way across floors, slid under doors, attached itself to an exposed foot, hand, arm and then devoured its screaming victim without making even a swallowing sound ... If you liked The Blob, then feast your eyes on this: Joey Shanks' Killer Silly Putty ... It's real ? and it eats magnets! (You don't have to watch the whole thing to get the idea ...)

Well, let's say it "swallows" magnets. What you have here is, in fact, Silly Putty, but doctored with a healthy sprinkling of mixed iron oxide powder. Iron, as you know, likes magnets. Iron and magnets attract. So when Joey Shanks who runs a production company in Chapel Hill was making this for Scott Lawson's YouTube Science and Engineering Channel he put a boron neodymium magnet next to the iron-rich Silly Putty. The magnet and the iron bits couldn't resist each other, and because Silly Putty is a fluid, it pretty much flows over the magnet and appears to "swallow it."

In real life, it does this rather slowly, taking a half hour, sometimes more, but Joey sped up the footage to create the illusion of a gelatinous monster devouring a hunk of metal (or in one poignant scene, an innocent happy-faced metal-boy).

What happens to the metal once it's inside the putty? Does it dissolve in a stew of putty digestive juices? No. Magnet lovers rest easy ? it's in there, whole, like Jonah inside the whale.

Does it sink to the bottom? Or stay near an edge, "hoping" to escape? Turns out, according to blogger Phil Plait, astronomer, lecturer, writing for Slate, ("It's Alive! ALIIIVVVEEE") the magnet keeps moving, deeper and deeper into belly of the puttyish mass until it reaches equilibrium, until there's roughly the same amount of iron top, bottom, left and right, holding it in place:

The process continued until the magnet was in the center, because it's only then that the forces are balanced. Newton's Second Law of Motion states that an unbalanced force on a mass will cause it to accelerate (though in this case that acceleration is itself balanced by the viscosity of the Silly Putty, leaving very slow but constant motion; it's like terminal velocity). As long as there's more iron on one side of the magnet than the other, it'll move. So eventually it reached the center of mass of the putty wad and stopped.

Which is wonderful, because now you can imagine yourself, being pretty much iron-free, grabbing onto the putty, ripping it open, reaching in, and heroically rescuing the magnet from its horrible fate ... like the hunter who rescues Little Red Riding Hood and her Grandma by slicing open the Big Bad Wolf! This is a physics lesson where you get to be a superhero. Is there anything better?

Well, dark chocolate is better. But that's another post.

Update: Hey! Commenty people, I'm sorry some of you (well, one of you ? "Captain Dave") don't like dark chocolate. No need to get persnickety, though, because in the end, you lose. Without dark chocolate, life is a pale thing. But since you are all wonderful, chocolate-loving or no, I thought I'd share this ? which just happened. When NPR producer Linda Holmes (who you may know from NPR's Monkey See blog) saw this post, she realized that by some crazy chance she happened to have her own iron-rich Silly Putty and a magnet.

Why? Linda told my producer, Andrew Prince, that she got them from a TV company, but not being sure what to do with them, she kept them in a can magnetically attached to a metal file cabinet next to her desk. But on seeing the video, she thought, "Ah, that's what they're for!" So she pulled the magnet out of its Silly Putty wrapper and brought them separately to Andrew and here, freshly minted, is Andrew's version of the same experiment. This may not be as exciting for you as it is for us, but how often do you get to see something cool in a video and get to repeat it, with all the parts handed you for free ? on the very same day? Life, sometimes, is just wonderful.

The dodo belongs to Andrew. It's extinct, I know, but it still loves dark chocolate.

Things Health/Fitness Professionals Need to Know About Multiple ...


1. LACK OF CERTAINTY. No one knows for sure what causes multiple sclerosis (MS), a chronic disease that affects the brain, spinal cord, and optic nerves. What is known for certain is that the immune system of people with MS erodes the myelin sheath that covers and protects certain nerves, which interferes with communication between the brain and specific parts of the body. Unfortunately, no single test for diagnosing MS exists.

    (AP) ? The two brothers suspected in the Boston Marathon bombings have their ethnic roots in Chechnya, a part of the Caucasus Mountains that has spawned decades of violence ? from separatist wars to suicide attacks, blood feuds and hostage sieges.

    Authorities have not linked Tamerlan and Dzhokhar Tsarnaev to any insurgent groups, and the Kremlin-backed strongman who now leads Chechnya says the brothers got their inspiration in the U.S., not the troubled region in southern Russia.

    "They weren't living here. They were living, studying and growing up in America," Chechen leader Ramzan Kadyrov said in an interview on Russian television. "They have been educated there, not here."

    The families of Tamerlan Tsarnaev, the 26-year-old killed in a gun battle with police in Massachusetts overnight, and his 19-year-old brother, Dzhokhar, left Chechnya long ago and moved to Central Asia, according to the Chechen government.

    Before arriving in the United States a decade ago, the brothers lived briefly in Makhachkala, the capital of Dagestan, a neighboring, violence-wracked Russian province where their father resides.

    The conflict in Chechnya began in 1994 as a separatist war, but became an Islamic insurgency dedicated to forming an Islamic state in the Caucasus. Dagestan has since become the epicenter of the insurgency.

    Russian troops withdrew from Chechnya in 1996 after the first Chechen war, leaving it de-facto independent and largely lawless, but then rolled back three years later following apartment building explosions in Moscow and other cities blamed on the rebels.

    Kadyrov has Moscow's carte blanche to stabilize Chechnya with his feared security services, which are accused of killings, torture and other rampant human rights abuses.

    The Tsarnaev brothers lived in the region only briefly as children, but appeared to have maintained a strong Chechen identity. Dzhokhar Tsarnaev's first name is the same as Chechnya's first separatist president, who was killed in a Russian airstrike.

    The suspects' uncle, Ruslan Tsarni of Montgomery Village, Md., urged Dzhokhar Tsarnaev to turn himself in, saying: "He put a shame on our family, the Tsarnaev family. He put a shame on the entire Chechen ethnicity."

    In the interview on Russian TV, Kadyrov offered his condolences to the Boston Marathon victims, but placed the blame squarely on the United States.

    He added on Instagram that "the roots of this evil are to be found in America," but offered no explanation. He also criticized U.S. authorities for failing to capture the older brother alive.

    Russia has relied on Kadyrov, a ruthless former rebel, to bring a degree of stability to Chechnya in recent years. But the Islamic insurgency has spread to neighboring provinces, with Dagestan ? sandwiched between Chechnya and the Caspian Sea ? now seeing the worst of the violence. Militants launch daily attacks against police and other authorities.

    Militants from Chechnya and neighboring provinces have carried out a series of terrorist attacks in Russia, including a 2002 raid on a Moscow theater, in which 129 hostages died, most of them from the effects of narcotics gas that Russian special forces pumped into the building to incapacitate the attackers.

    In 2004, militants from Chechnya took more than 1,000 people hostage at a school in Beslan, and the siege ended when gunfire erupted after explosions tore through the gym. More than half of the 330 people who died were children. There also have been numerous bombings in Moscow and other cities.

    The Obama administration placed Chechen warlord Doku Umarov on a list of terrorist leaders after he claimed responsibility for 2010 suicide bombings on Moscow's subway that killed 40 people and a 2009 train bombing that claimed 26 lives.

    Russia faced strong international criticism for its indiscriminate use of force against civilians and other rights abuses in Chechnya. The two separatist wars killed an estimated 100,000 people, and Russian bombing reduced most of Chechnya's capital, Grozny, and many other towns and villages to rubble, sending tens of thousands fleeing.

    The federal forces suffered heavy casualties in the hands of lightly armed rebels, who relied on their centuries-old warrior culture and knowledge of rugged terrain to offset the Russian edge in firepower. The Chechens' successes were reminiscent of their exploits in 19th-century battles against a czarist army that spent decades trying to conquer the Caucasus.

    In recent years, militants in Chechnya, Dagestan and neighboring provinces have largely refrained from attacks outside the Caucasus.

    Russian officials and experts have claimed that rebels in Chechnya had close links with al-Qaida. They say dozens of fighters from Arab countries trickled into Chechnya during the fighting there, while some Chechen militants have fought in Afghanistan.

    President Vladimir Putin's spokesman, Dmitry Peskov, said Friday that the Russian leader had long warned the West about the dangers posed by the Chechen rebels.

    "Back at the time when we had a war raging in the Caucasus, Putin repeatedly said that the terrorists shouldn't be divided into 'ours' and 'theirs,' they mustn't be played with, differentiated into categories," Peskov said, according to Russian news agencies. It was an apparent reference to Western reluctance in the past to agree to the Kremlin branding rebels in Chechnya as terrorists.

    The U.S. has long urged Russia's government and separatist elements in Chechnya not aligned with al-Qaida or other terrorist organizations to seek a political settlement.

    Washington provided aid to the area during the high points of fighting in the 1990s and in the early 2000s, and has demanded human rights accountability. But the U.S. always backed the territorial integrity of Russia, never endorsing the separatists' desire for an independent state. And it has supported Russia's right to root out terrorism in the region.

    Dozens of Chechens have trained in Pakistan's northwest frontier of Waziristan, but most have returned to Russia to fight.

    Recently, however, the al-Qaida inspired group Tehrik-e-Taliban Pakistan has made strides at recruiting European fighters for attacks against the West, according to Noman Benotman, a former jihadist fighter who now works for the London-based Quillium Foundation.

    The TTP, which has supported attacks in response to U.S. drone strikes, was linked to the failed 2010 attack in New York City's Times Square.

    In recent years, people from Chechnya have faced charges in several European countries.

    In 2011, a Danish court sentenced a Chechen-born man to 12 years in prison for preparing a letter bomb that exploded as he was assembling it in a Copenhagen hotel.

    Last month, Spain's Interior Ministry said French and Spanish police arrested three suspected Islamic extremists in an operation in and around Paris. A statement said the suspected activists were of Chechen origin and believed linked to a terror cell dismantled in August in southern Spain.

    That same month, a Turk and two Russians of Chechen descent were arrested and jailed in Spain on charges of belonging to an unidentified terror organization and possession of explosives. They have since been released while investigations continue.

    The U.S. security think tank Stratfor said Friday that if the Tsarnaev brothers had any link to al-Qaida, or one of its franchise groups, it would "likely be ideological rather than operational, although it is possible that the two have attended some type of basic militant training abroad."

    Stratfor added that the Boston bombings highlighted the fact that "the jihadist threat now predominantly stems from grassroots operatives who live in the West rather than teams of highly trained operatives sent to the United States from overseas, like the team that executed the 9/11 attacks."

    "There will always be plenty of soft targets in a free society, and it is incredibly easy to kill people, even for untrained operatives," it said.

    Zimbabwe Extends Poll Funding Appeal to South Africa, Angola

    Harare ? The cash strapped Zimbabwean government has extended its appeal for election funding to South Africa and Angola, other than the United Nations.

    The poll budget has been reduced from 132 million U.S. dollars to 100 million U.S. dollars following the acquisition of some of the required vehicles and equipment ahead of the March 16 constitutional referendum.

    Minister of Finance Tendai Biti told journalists on Monday that the government had appealed to fellow southern African countries for funding since it did not have the capacity to finance the elections.

    Zimbabwe is expected to conduct harmonized presidential, legislative and local government elections soon, following the passing of a new constitution which now awaits parliamentary endorsement and presidential assent.

    Biti and Justice and Legal Affairs Minister Patrick Chinamasa had since written to the United Nations seeking 132 million U.S. dollars for the polls.

    Nurse backs off mercy claim in 29 NJ, Pa. deaths

    TRENTON, N.J. (AP) ? At his sentencing hearings in 2006, serial killer nurse Charles Cullen didn't explain why he killed at least 29 hospital and nursing home patients in New Jersey and Pennsylvania.

    He had told investigators they were mercy killings. But a prosecutor said Cullen was driven by a compulsion to kill and was no "angel of death."

    In an interview with CBS' "60 Minutes" that had been scheduled to air Sunday, Cullen at first says he thought he was helping people by ending their suffering. Many of the victims of his lethal drug overdoses were old or gravely ill.

    But Cullen tells a different story when reminded some victims weren't close to death. He says there was "no justification" and felt "overwhelmed at the time."

    CBS announced Friday afternoon that the segment will be held for at least a week due to ongoing coverage of the Boston Marathon explosions.
