Alaska, the biggest state in the United States, was sold for a total of $7.2 million, or roughly 2 cents per acre. In 1867, the state was bought. America made its $7.2 million investment back more than 100 times over in the 50 years that followed. Talk about a good investment.

While Walt Disney invented Mickey Mouse and gave the voice, the visual was developed by animator Ub Iwerks, who designed all of the famous characteristics. You'll never look at the adorable mouse the same way again.

If you look closely at your zipper, you'll notice the letters YKK, which stand for Yoshida Kogyo Kabushikikaisha. This business, founded in Tokyo in 1934, is believed to create 7 billion zippers every year.

The Nazis pondered releasing an army of potato bugs on their adversaries, which they felt might be dumped on England to ruin its crops and bring severe starvation. However, experts recognised that almost 40 million insects would be required for the operation if it was to be successful—though several million had been hoarded by the time the war ended.

Many variations of the suit exist in different planets, and they are all fire-resistant, bulletproof, and electrically insulated. The cape may also be used as a parachutist or hang glider. High-tech instruments, like as night vision and communication devices, are also used to create the renowned cowl. It's also used to keep his identity hidden from some superhumans.

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.

Did you realise that the word "Pennsylvania" is misspelt on the Liberty Bell? Actually, worded incorrectly is perhaps a bit harsh: when the bell was constructed in 1752, it was one of several permissible spellings. The ancestors of the United States also committed several obvious language errors in the Constitution.

The origins of this strange-sounding celebration may be traced back hundreds of years, beginning in the early 1900s. People did not have refrigerators in the 1900s, so they hung a piece of cloth in their larders. It is thought that doing so provided the home good fortune, tranquilly, and wealth. The tradition evolved to accommodate the contemporary kitchen throughout time. Every year on May 29th, families throughout the world place a pillow on top of their refrigerator.

Several nations, like Mexico, Germany, and Austria, see the urge to escape from jail as a natural human instinct rather than a criminal act. As a result, a jail break is not considered a crime in and of itself, but before you start planning the ideal escape, keep in mind that they will still try to find you and you may be penalized for any illegal conduct you do during or after your escape.

The largest padlock in the world (according to Guinness World Records) was created by a team of students and teachers at Russia's Pavlovo Arts College and measures 56.8 inches tall, 41.3 inches wide, and 10.2 inches deep. The total weight of this heavy lock, including the key, is 916 pounds. Whatever it's guarding presumably weighs a lot more!

Human settlers first arrived in Madagascar very recently, probably as late as 500AD, some 300,000 years after Homo sapiens originally appeared in Africa.

An ultra-luxurious lodge has been opened on Nosy Ankao, the biggest of five islands off Madagascar's northeast coast. Miavana (only accessible by helicopter) is a destination for "blue safaris," which include opportunities to see turtles, whales, and dolphins, as well as scuba diving and fishing. There's also a fantastic spa. But start saving now - doubles start at £3,220 per night.

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).

Christian Dior technically invented designer sunglasses when, in the early 1960s, they licenced their brand to be used to produce luxury sunglasses for discerning fashionistas. Using Optyl, his own lightweight thermo-hardening material, he converted expensive sunglasses into more wearable everyday items. The properties of this material also allowed for a wider choice of models, from broad and original lines to previously discovered hues and delicate degradé of translucent, brown, green, and grey colours that still mark Dior's beautiful and refined style.

Ecologists estimate that treating one ton of ore yields 1–2 grams of gold. The same quantity of precious metal may be obtained by processing all gold-bearing components from 41 mobile phones. A tonne of electronics includes almost 300 grams of gold. However, the cost of the devices is prohibitively expensive for this gold-mining method to be profitable.

Many people find this assertion odd, yet eating pizza for breakfast is really healthier than eating cereal. According to famous American nutritionist Chelsey Amer, pizza includes lipids, carbs, and protein that will keep you fuller for longer than porridge with milk. Cereals, of course, include carbohydrates and sugar. Of course, this does not mean that you should only eat pizza for breakfast, but it also does not mean that you should only eat cereal in the morning.

Sony built the cameras to record footage more effectively in low-light conditions. So their error was unintentional. Because they could record in infrared, the camcorders could see through clothing. During the day, though, you could see right through someone's outer layer of clothing! Sony sought to recall all of the cameras as soon as they recognised their blunder, making it their largest product recall to date.

In the 1990s, Korean pop musicians incorporated American popular music styles. Seo Taiji and Boys were the forerunners of this style, releasing the infamous single "I know" in 1992. It was so controversial that most critics despised their music and predicted that they would never make it. Nonetheless, the group quickly became enormously popular. Yang Hyun Suk of YG Entertainment was a member of the group, which is regarded as part of K-revolutionary Pop's period.

Where the Wild Things Are was originally titled Where the Wild Horses Are, and Maurice Sendak intended to write about horses; however, the author and illustrator quickly realised he was terrible at drawing horses and decided it would be better to draw 'things' instead; thus, one of the most memorable children's stories of all time was born.

Fischer was charged in 1992 with violating economic sanctions imposed on Yugoslavia. He came out of retirement to earn $5 million in a rematch against his old nemesis, Boris Spassky. Fischer never returned to the United States and eventually settled (and died) in Reykjavik after renunciating his American citizenship.

Humans have celebrated the start of each new year with parties, festivals, and religious ceremonies for millennia. However, we haven't always agreed on the beginning of the year. Four thousand years ago, the first new moon after the Vernal Equinox was regarded as the dividing line between the previous year and the new one in ancient Babylon. After Julius Caesar made major changes to the Roman calendar in 45 BCE, January 1 became the start of the new year for the first time. Ancient Romans commemorated the day with sacrifices to Janus, the Roman god of beginnings (after whom the month of January is named), as well as gift exchanges and large parties.

A particular female servant with the Queen's shoe size breaks in her new shoes for her. Although Elizabeth II has favored comparable shoes of the same brand for many years, she does not want to suffer the agony that new shoes generally bring.

Since 1995, Charles Martinet has provided voices for Mario, Luigi, Wario, Waluigi, and other Mushroom Kingdom characters. It's all thanks to a friend who urged him to attend an audition at a tradeshow in Las Vegas to which he had not been invited. When Martinet arrived, the audition team had already begun to pack up their belongings. Fortunately, they still let him audition for the part.
