In 2012, when Boeing wanted to test its wireless signal on new planes, they placed massive piles of potatoes on the seats. Potatoes absorb and reflect radio and wireless signals in the same way that humans do due to their high water content and chemical makeup.

Malaysia is home to the world's biggest cave chamber. The Sarawak Chamber at Gunung Mulu National Park is enormous, with enough capacity for 40-50 Boeing 747s. It's another matter if you could actually park these jets in the Sarawak Chamber...

However, one of the most unexpected facts about Greece is that the bulk of the nation is really made up of mountains. It is one of the most mountainous nations in Europe, with mountains covering 80 percent of the land area. Remember to bring a decent pair of walking shoes!

The world we "see" is a figment of our imagination. Our minds do not generate images in the same way that a video camera does. Instead, the brain builds a model of the world using data from modules that measure light and shade, edges, curvature, and so on. This allows the brain to easily paint out the blind spot, which is the area of your retina where the optic nerve connects and has no sensors. It also compensates for our eyes' rapid, jerky movements, known as saccades, creating the illusion of steady vision.

In Korea, age is given precedence over all other considerations. When conversing with someone of a higher rank or age, formal language must be used. Similarly, when conversing with a junior/someone younger, you can use informal language (banmal, ). Unless two people agree to use banmal at the same time, this usually remains the case. Even in a k-pop group with members who are mostly around the same age, a few months difference in birthdate can make a big difference.

As if the Nazis weren't already evil enough, they got dangerously close to producing plutonium, the material that powers nuclear bombs. When the Germans invaded Norway, they seized control of a facility in the Telemark region that manufactured heavy water, which was used to generate plutonium.

It goes without saying that the ancient Babylonians were excellent mathematicians. They understood the Pythagorean theorem, for example, nearly 4,000 years ago, or more than a millennium before Pythagoras himself was born. Their mathematical prowess naturally extended to astronomy, where they routinely used arithmetic to catalogue celestial body movements and improve their astronomical predictions.

Yes, indeed! You may walk by foot between the United States and Russia during certain times of the year, owing to two islands known as Big and Little Diomede. Big Diomede is located in the Russian Federation's easternmost region, whereas Little Diomede is located in Alaskan territory. When the water freezes in the winter, daring visitors can cross the 2.4-mile distance between the two islands. However, you do it at your own peril; while experts believe the voyage is technically feasible, it is risky and not encouraged.

If you go to Moldova for a vacation, you won't have to compete for space with other tourists: just 121,000 foreigners are believed to have entered the nation in 2016 (according to the UN World Tourism Organization), making it the least visited country in Europe. According to Priceonomics, only Bangladesh and Guinea are less touristic places on a worldwide scale (in terms of tourists per inhabitant).

It can contain nearly 66 million gallons of crystal clean saltwater. The pool opened in December 2006 after five years of building work at a cost of about one billion dollars ($US) and an annual maintenance cost of roughly two million.

Few odours are as appealing as "new car smell," and it's not just because it's nice to be in a brand new car. However, while the scent may be strangely satisfying, it is actually a combination of 50+ chemicals (known as "volatile organic compounds") that are released into the car and decay quickly over time. The concentrations found in a typical new car are not dangerous, but VOCs found in nail polish, auto fuel, and petroleum contribute significantly to the new car smell.

This is one of the Japanese facts for children! Because the ice cream will ultimately melt, the term is a little deceptive. It appears that the non-melting ice cream will take several hours to thaw. Consider this, kids: this is unquestionably the finest of the kid's Japan facts! Yummy! The finding happened by chance as scientists were working with strawberry chemistry. This was done to assist farmers affected by the 2011 earthquake.
