Because of the excitement surrounding the Olympics, we decided to make a series about the psychology, physiology, biology, chemistry and physics of the games!
While drilling in 1971, Soviet geologists tapped into a cavern filled with natural gas.The ground beneath the drilling rig collapsed, leaving a large hole with a diameter of 70 meters (230 ft). To avoid poisonous gas discharge, it was decided the best solution was burn it off. Geologists had hoped the fire would use all the fuel in a matter of days, but the gas is still burning today. Locals have dubbed the cavern “The Door to Hell”.
“The Door To Hell” may sound like a science fiction-horror movie, but it’s not. It is a real place in Turkmenistan.
Hank Green of SciShow explains that in the 1970′s, Soviet scientists found an amazing depot of natural gas, but while attempting to retrieve it accidentally caused the ground to collapse.
The scientists realized it would be better to set the now free methane on fire than let the dangerous, combustible gas vent into the environment.
They thought the gas would be burn up in a few weeks, but 42 years later the crater is still burning.
An easy way to destroy a magnet. In case you ever need to!
Magnets are amazingly strong… but there’s a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!
Vision and the way our brains perceive what we are seeing are incredible. Just think of optical illusions, 3D images, the fact that your eyes are processing the world around you upside-down! A fun trick to play on your eyes and brain uses a zoetrope. This fantastic tool is able to change multiple still images, into a moving animation that would make Walt Disney jealous.
No matter how much calorie information is presented to the consumer, people still choose the food they like, not what’s supposed to be healthier for them.
When calorie counts are posted for various foods, be aware that your mileage may vary. Sometimes it’s due to a generous server and just a dollop more than the standard size. And the fact that a Subway sandwich comes in as fewer than the stated calories can be attributed to the fact that Subway footlongs are eleven inches. But some foods have calorie counts that don’t seem to be related to reality at all.
If foods are going to have mandated calorie labels, why aren’t they mandated to be accurate? Because testing and enforcement is time-consuming and expensive, as you’ll see in this video by Casey Neistat of the New York Times. -via Nag on the Lake
