Today I found out what hemisphere you are in does not affect the way water spins down your drain. So why do some textbooks, most tour guides, and pretty much all TV shows like The Simpsons get it wrong? The myth that water in your drain will spin differently depending on what hemisphere you are in primarily stems from taking […]

Today I found out humans have a lot more than five senses. It turns out, there are at least nine senses and most researchers think there are more like twenty-one or so. Just for reference, the commonly held definition of a “sense” is “any system that consists of a group of sensory cell types that respond to a specific physical […]

Today I found out how the completely blind dream. It turns out that if they went completely blind before around the age of 5-7 years old, they will typically dream without any visual experiences. In the very few cases where some report having visual experiences in their dreams, these experiences are more in the abstract sense where they feel like […]

Today I found out that sugar does not make kids hyper. In fact, it has been proven in numerous studies that it doesn’t affect their behavior at all. In one such study, it was found that mothers who think their kids have been given sugar (even though their kids haven’t been given any), will almost always say their kids are […]

Today I found out why popcorn pops. First a little background, Popcorn or “zea mays everta” is a special kind of Flint corn, also known as “Indian corn” and sometimes “Calico corn”. Flint corn is readily recognizable as the kernels have a hard outer shell, likened to flint, hence the name. This hard outer shell is essential in making popcorn […]

Today I found out nearly all commercial banana plants are perfect clones of one another and most originate from one single plant from Southeast Asia. Now to be clear, there are approximately 1000 different types of banana plants in the world today and within each variety most are generally clones of one another, although some do have a bit of […]

Today I found out a Coffee bean is not actually a bean, rather it is a seed. Now I know you are saying to yourself right now, “Aren’t beans seeds and seeds beans?” Surprisingly, that is not the case. (who knew?) In fact, though beans are always seeds, seeds are not always beans. A bean is just one kind of […]

Today I found out what causes the pain in your side you may occasionally feel while running or doing other jarring activities. This pain, known often as “side stitch” and more technically as “exercise related transient abdominal pain” (ETAP), often occurs while running, swimming, and horse riding, among others; it is caused by various stresses on your diaphragm that result […]

Today I found out what causes “eye floaters”. For those who’ve never experienced this phenomenon, eye floaters are little oddly shaped objects that appear in your vision, often when one looks at bright light such as a blue sky. Their shapes vary greatly, but will often appear as spots, cobwebs, or randomly shaped stringy objects. These are not optical illusions, […]

Today I found out the difference between jelly and jam. The difference between jelly and jam is that jelly is made strictly from the juice of fruit while jam is made from crushed fruit. Specifically, jelly is made by crushing fruit, then straining out everything but the juice. The juice is then boiled, typically with sugar and pectin added, the […]

Today I fount out that all lifesavers spark when chewed, not just the Wintergreen Lifesavers (also known as Wint-O-Green). The flash you see when these hard sugar candies are crunched is caused by triboluminescence, which is similar to the electrical charge build-up that produces lightning, except on a much smaller scale here. With most hard sugar candies, this flash tends […]

Today I found out that the tongue doesn’t have zones specializing in specific tastes, contrary to popular belief. So why did your third grade teacher tell you they did and make you memorize each zone, then mark you down when you got one of them wrong which resulted in you not getting to go play with your friends that night […]

Today I found out there was once a woman who had immortal cells. These immortal cells have multiplied to the point that if you were to weigh all of them that live today, they’d weigh about 50 million metric tons, which is about as much as 100 Empire State Buildings. So who was this woman and why are scientists keeping […]

Today I found out why the sky is blue. For the short answer, when light from the sun enters our atmosphere it collides with molecules in the air. The blue part of the light gets scattered more than the other parts during these collisions and thus makes the sky appear to our eyes as blue. If the light from the […]

Today I found out Moon dust smells like spent gunpowder. This is according to the astronauts that have had the opportunity to smell fresh Moon dust that had been tracked into the lunar module after excursions out on the surface of the Moon. The astronauts didn’t just smell the dust though, they also touched and tasted it. They say it […]

Today I found out how glow in the dark stuff works. Glow in the dark products all contain some type of phosphor. Phosphors are any substance that radiates light after being energized in some way. There are literally thousands of chemicals that are phosphors. These chemicals all have varying degrees of brightness, color, and length of time they glow after […]

Today I found out the red juice in raw red meat is not blood. Nearly all blood is removed from meat during slaughter, which is also why you don’t see blood in raw “white meat”; only an extremely small amount of blood remains within the muscle tissue when you get it from the store. So what is that red liquid […]

Today I found out, before the 17th century, almost all cultivated carrots were purple. The modern day orange carrot wasn’t cultivated until Dutch growers in the late 16th century took mutant strains of the purple carrot and gradually developed them into the sweet, plump, orange variety we have today. Before this, pretty much all carrots were purple with mutated versions […]
