It would only take 29 dominoes to knock over the Empire State Building. Find out how


Physics can be terrifying and awesome at the same time. A single, tiny domino, only five millimeters high and a single millimeter thick could knock down a building as big as the Empire State building in just 29 steps.

Dominoes can knock over another domino up to one and a half times it's size. If you started with that small domino, about the size of a fingernail, it would only take 29 dominoes, each one one and a half times larger than the previous, to get to the size of New York's crown jewel building—and it would crumble.

Gravitational energy is stored in each domino when they are stood up, which requires just the slightest push to get the energy to spill to the side and release that energy that goes straight into the next domino it hits. With every domino the energy continues to amplify, gaining the power to knock down just about anything in it's way once it gets big enough.

The idea of massive amounts of energy getting exponentially bigger can be a terrifying thought on a grand scale.

Cocaine and heroin aren't the most dangerous drugs. The stuff you find in your medicine cabinet is far worse!


The War on Drugs rages on, trying to protect everyone from their harming affects. But what if some of the most dangerous drugs were so easy to get your hands on, you could just pick them up off the shelf? Turns out that may be the case, since the rate of fatal painkiller overdoses in women have risen over 415 percent since 1999.

Your medicine cabinet may be full of the most potent and lethal drugs. Prescription pain relievers cause four times the deaths that drugs like cocaine and heroin cause—combined. In 2010 alone, 38,329 drug overdose deaths, a whopping 68 percent, are all attributed to prescription drugs.

CDC Director Dr. Tom Frieden attributes the severe increase to extreme marketing tactics taken by pharmaceutical companies. Commercials, magazine ads, and word of mouth spread their popularity to alarming rates. Figures showed that 70 percent of Americans were given at least one drug prescription in the last year, with dangerous opioid painkillers ranking among the three most common types.

While women suffered a 415 percent increase, men only showed a 265 percent increase in prescription painkiller related deaths. The reason is women are more likely to be prescribed the dangerous stuff, receive higher doses, and shop around for doctors, receiving several prescriptions.

The element Selenium gets more conductive when it is in the light!


Selenium is a naturally occurring element with a periodic number of 34. It was discovered in 1817 and is found impurely in metal sulfide ores.

Selenium has an interesting property that most elements do not have called photoconductivity. Photoconductivity is a phenomenon where a substance actually becomes more conductive when visible light is shown on it!

Not only does Selenium become more conductive when light is shown on it, but it is actually an insulator when there is not light on it!

Selenium is mostly used in glass production, with over 50% of its consumption used in giving glass a red color after the selenium is added.

For all the Doctor Who fans out there, I cannot help but wonder if the "Weeping Angels," a reoccurring foe of the doctor that can only move when they are not seen, aren't made of some other element that has an anti-photoconductivity phenomenon!

Some awesome lists!

There is not enough space in the universe to write down the number googolplex. But can you write down a googol?


There are numbers so ridiculously huge that there just is not enough space in the universe to write them down. What's even more amazing, is that these astronomically large numbers are actually of utmost importance, and even crucial, for understanding the world.

The two largest meaningful numbers are the googol (which has since become world famous in the form of Google) and the googolplex. The googol got its name from a nine year old nephew of mathematician Edward Kasner. He asked his nephews for any ideas they might have to name a really big number, and that is what nine year old Milton Sirotta came up with.

Kasner decided that 10^100—or, the number one followed by one hundred zeroes—would henceforth be known as a googol. Young Milton suggested an even larger number, the googolplex. He said it must be a number 1 followed by as many zeroes as could be written down before one gets tired.

Kasner felt it needed a better definition. It would be 10^googol, or 1 followed by a googol of zeroes. Therefore, a googolplex is 10^10^100. Carl Sagan once pointed out that it would physically impossible to write down all the zeroes in a googolplex, because there simply isn't enough room in the universe!

Americans eat a dramatically higher amount of sugar than they did 200 years ago! Find out how much!


Processed foods, supermarkets, and fast food have revolutionized the way Americans get that tasty, bad-for-you sugar into their bodies. In fact, the amount of sugar Americans consume every five days now is about the same that they consumed in a year just 200 years ago.

Sugar is the most popular ingredient added to foods in the United States. It's added to everything from sweets to processed foods to "healthy" things like peanut butter. The biggest culprit of sugar in the American diet? Soft drinks. A single teaspoon of corn syrup adds up to 20 calories.

The average American ate 2 pounds of sugar a year back in the early 1800s. That is increased to 123 pounds of sugar a year in 1970. Today? 152 pounds of the sweet stuff. That's the same as eating 3 pounds of sugar a week!

Nutritionists suggest only 10 percent of American's diets should come from sugar. Based on a 2,000 calories a day diet, that's only about 13.3 teaspoons a day. That is dwarfed by the reality of a whopping 42.5 teaspoons a day for the average American. Next time you ask for sugar in your coffee, maybe you should think twice!
