Did you know... Showers really do spark creativity.
Showers aren't just good for your hygiene—they're good for your creativity, too. For a 2012 study published in the journal Psychological Science, researchers gave volunteers creativity problems to solve followed by a period of rest. During that period, some were assigned demanding tasks, while others did simpler tasks that allowed their minds to wander (just like a shower does). Those doing the simpler tasks during the resting time were more likely to solve the original creativity problems.
Did you know... Abraham Lincoln's bodyguard left his post at Ford's Theatre to go for a drink.
You already know that Abraham Lincoln was shot and killed by John Wilkes Booth while watching a performance at Ford's Theatre in Washington, D.C., on April 14, 1865. But what you might not have been aware of is that the president had a bodyguard named John Frederick Parker with him on that fateful night, according to Smithsonian Magazine.
Unfortunately, Parker was a police officer with a less-than-stellar reputation. After arriving three hours late for his shift, the officer left his post protecting the president to get a drink at the Star Saloon next door to the theatre. It was during this time that Booth entered the box seats where Lincoln was sitting and shot the president.
Did you know...Dolphins have been trained to be used in wars.
Dolphins are known widely as adorable, intelligent animals. What is not as widely known is that these crafty creatures were used by the U.S. and Soviet Union during the Vietnam War and the Cold War. Both countries studied the creatures for their sonar capabilities, but also trained them to detect mines, bring equipment to divers, find lost equipment, and guard submarines amongst other nifty tricks.

Did you know... Playing the accordion was once required for teachers in North Korea.
The most popular instrument in North Korea is the accordion, so much so that all teachers used to be required to play to get their teaching certifications. Because the accordion is portable in a way that, say, a grand piano isn't, it was thought of as the "people's instrument" that could be taken outside and played for laborers in the fields.
Did you know... Children's medicine once contained morphine.
If you were a baby in the middle of the 1800s and you cried while teething, your parents might have given you Mrs. Winslow's Soothing Syrup. This "medicine" claimed that "it soothes the child, it softens the gums, [and] allays all pain." It may have done plenty of soothing, but it was also extremely dangerous—this concoction, like many patent medicines of the time, contained morphine.
Did you know... Plastic Easter eggs and plastic Easter grass were invented by a man who holds more patents than Thomas Edison.
If you've ever enjoyed an Easter basket with plastic eggs and grass, then you can thank Donald Weder, the man who invented both. Weder not only holds the patents on these holiday staples, he also holds a total of 1,413 U.S. patents—including ones for water-based inks, flower-pot covers, and decorative wrappers. That's compared to Thomas Edison, who held just 1,093 U.S. patents.
Did you know... Water makes different pouring sounds depending on its temperature.
If you listen very closely, hot water and cold water sound slightly different when being poured. The heat changes the thickness, or viscosity, of the water, which changes the pitch of the sound it makes when it's poured. What we feel as heat comes from the molecules of the water moving faster. Cold water is thicker and therefore makes a slightly higher-pitched sound.
Did you know... Most laughter isn't because things are funny.
Every culture in the world laughs, but surprisingly, most of our laughter isn't necessarily a response to humor. Less than 20 percent of laughter comes after jokes, according to neuroscientist Robert Provine; the rest is a reaction to regular statements and questions like, "How have you been?" The ensuing laughter, however brief, helps form social bonds since people who laugh together grow closer.
