The Brooklyn Public Library is one of America’s largest public libraries—and now, its lobby is home to what’s being billed as the world’s smallest mollusk museum (and its first, no less). The vending machine-sized installation contains 15 different educational “displays,” all of which highlight fun facts about bivalves, snails, octopuses, and other soft-bodied creatures, according to The Washington Post.

Installed on November 10, the mollusk museum is the brainchild of Amanda Schochet, a computational ecologist, and media producer Charles Philipp. In 2016 they co-founded MICRO, a nonprofit organization that makes and distributes compact science museums.

“Science museums are amazing,” the duo said in a video about their company, which is supported by Science Sandbox, an initiative of the Simons Foundation. “There’s just not enough of them. They’re all in wealthier neighborhoods. It’s fundamentally important for everyone to have access. So we decided to reinvent the museum, taking everything that we love about museums and putting it inside a box that can go anywhere.”

The factory-made museums are designed in collaboration with scientists, and created using 3D printing techniques. They’re easily reproduced, and can be set up anywhere, including libraries, airports, or even the DMV.

The BPL’s Smallest Mollusk Museum is MICRO’s first public project. Why mollusks, you might ask? For one thing, they survive in every habitat on Earth, and have evolved over hundreds of millions of years. Plus, a mollusk museum of any type—large or small—didn’t exist yet, as Schochet learned after she once misheard Philipp say he was going to the world’s “mollusk museum.” (He was instead going to the “smallest” one, located inside a Manhattan elevator shaft.)

The Smallest Mollusk Museum is “packed with exhibits including miniature movie theaters, 3D-printed sculptures of octopus brains and leopard slug hugs, optical illusions showing visitors what it’s like to experience the world as mollusks, and a holographic mollusk aquarium,” Schochet tells Mental Floss. “We've identified nearly 100,000 species of mollusks, but there could be as many as 200,000—they’re all around us, all the time. Every one of them is a lens onto a bigger universe.”

Librarians have also joined in on the mollusk mania, prepping an accompanying series of books for kids and adults about the many creatures featured in the museum's exhibits.

The Smallest Mollusk Museum will gradually circulate through several of the library system’s branches. Meanwhile, MICRO’s next public offering will be a second mollusk museum, which will open in the Ronald McDonald House in New York City in December 2017. Additional locations and projects—including a small physics museum called the Perpetual Motion Museum—will be announced soon.

26 Fascinating Facts About the Human Body

You may not think about it very often, but there's so much to learn about the human body. For instance, did you know that people are actually covered in invisible stripes? In this article, which was adapted from an episode of The List Show, we take a look at some fascinating facts about the human body you might not know.

1. Only humans have chins.

Humans are the only animals with chins. While you may think every animal has one, that’s just what we tend to call the bottom of the head. But in reality, a chin is a very specific bone feature that extends forward from the lower jaw. Some experts propose that elephants and manatees have chins, but others argue that they’re such fundamentally distinct structures they shouldn’t be compared to humans. Experts still aren’t sure why people evolved to have chins; the reason might have to do with eating or speaking, or they may just have emerged as a side effect from some other useful feature.

2. Humans have a strange bone called the hyoid.

A peculiar bone humans have is the hyoid. This is the one bone that doesn’t form a joint with another bone. Instead, it’s connected to muscles and ligaments. The hyoid sits between the jaw and the voice box and it’s used to keep all the lower mouth muscles in place. It also helps with swallowing and talking.

3. People that have more hair and innie belly buttons are more prone to lint.

Hairy people with innie belly buttons are more prone to belly button lint, which comes from fibers that rub off of clothing over time. Your stomach hair grabs onto the fibers and pulls them into your belly button.

Starting in 2011, a group of scientists started the Belly Button Biodiversity Project to learn about what's going on inside these little caves of mystery, and as it turns out, it's quite a lot. Samples from about 60 people revealed over 2300 total species of bacteria. And of those, only eight were identified as common, appearing in over 70 percent of belly buttons.

4. While it varies person to person, fingernails grow faster than toenails.

Your fingernails grow faster than your toenails. Though it varies from person to person, typically, fingernails grow about a tenth of a millimeter each day, while toenails grow at around half that pace. There’s a correlation between nail growth speed and the length of the nearest bone. This means that your longest fingers have faster-growing nails than your shorter fingers.

5. Fingernails grow faster on your dominant hand.

Your fingernails grow faster on the hand that you write with. No one knows why.

6. As you age, your nails change.

Specifically, they grow more slowly and then nail cells, known as onychocytes, start accumulating. That’s why older people have thicker toenails. Fingernails aren’t as noticeably different because people manage them better, plus our toes endure a lot of damage throughout our lives.

7. It's a misconception that people's hair and nails continue to grow after they die.

What’s actually happening is the skin dehydrates and then recedes. So it looks like the hair and nails are getting longer, but in reality it's actually the skin that's getting shorter.

8. Breastfeeding will not cause breasts to sag.

It's a common misconception that breastfeeding causes breasts to sag. Pregnancy itself might affect breasts in that they may stretch and then recover differently. But research on breastfeeding confirms it will not cause breasts to sink. A behavior that will, though, is smoking.

9. Hands and feet contain over half the bones in an adult body.

With around 27 bones in each of your daddles—that’s an old slang word for the hands—and about 26 bones in each of your plates of meat—which is another old slang term for feet—these appendages account for over half of an adult’s bones, of which there are around 206 total. But that’s not always true. Feet mostly contain cartilage at birth, then bones form over time. They don’t fully harden until humans are in their early twenties.

10. You can fracture a rib just by sneezing.

While it's rare, it is possible to fracture a rib by sneezing. In 1885, there was an article in the Journal of the American Medical Association about a 72-year-old man who fractured his eighth rib while sneezing. Sneezer, by the way, is a 1940s Australian slang term meaning “excellent, wonderful,” which could definitely describe a good sneeze—but probably not one that would break a rib.

11. You can see stars if you rub your eyes.

If you've ever seen stars while rubbing your eyes, you’re not imagining it. The cells in our eyes are interpreting the pressure as an input, and treat that the same way they’d treat a light input.

12. Goosebumps are pretty much useless.

Goosebumps are frequently associated with adrenaline being released in the body, like when we’re feeling a particularly strong emotion, for example. They used to be important when people had way more hair on their bodies because goosebumps would elevate that hair and make a person look bigger when they were in danger. But now, they’re a pretty useless feature.

13. Spleens help the immune system.

The spleen is surprisingly not totally useless even though that was the belief up until the 1950s. It’s OK to get your spleen removed, but it does assist the immune system. While blood is in the spleen, the immune system creates the necessary antibodies to fight bacteria in that blood. A fetus’s spleen also creates red blood cells.

14. The appendix seems to help the immune system.

It's OK to get your appendix removed, but the organ also aids the immune system. In 2018, Dr. Mohamad Abouzeid, assistant professor and attending surgeon at NYU Langone Health told Mental Floss, "[The appendix] has a high concentration of the immune cells within its walls." Experts don't know exactly how the appendix affects the immune system, but it seems to play some role in keeping us healthy.

15. A fetus's face forms in the first three months after conception.

During the first three months after conception, a fetus’s face comes together, fusing in the area of the top of the lip. That means the dent under the nose, which is called the philtrum, is evidence of a person's time in the womb.

16. Babies don’t just see in black and white.

A newborn baby has pretty terrible vision. But it’s not true that they can only see in black and white. In reality, if there’s a large amount of the color red, they can identify it, but only if it appears in front of gray. Newborns have about 5 percent of the visual acuity that adults do, but it improves quickly and takes only around six months before they can see about as well as a grown-up. Though there are some eye tests that babies can school adults on, which are ones centered around subtlety. For example, up until 6 months old, a baby can tell monkeys apart, while older babies and adults can’t do that.

17. The liver is very good at regenerating itself.

In fact, with just 25 percent of the original liver tissue, it can regenerate. Liver transplants are generally only needed if someone has experienced severe damage to the organ or an injury.

18. Some people are born with three kidneys.

Some people had a kidney split while they were still in the womb, so they're actually born with three. This makes them prime candidates for donation, but the problem is people often don't know when they have three kidneys.

19. A person's large intestine can be stretched 5 feet and the small intestine can stretch 20 feet.

The intestines are pretty long: The small intestine stretches to about 20 feet and the large intestine hits 5 feet. The surface area of your intestines could take up two entire tennis courts, although some Swedish researchers have downgraded it to studio apartment size. Compare that with a blue whale, though, which has over 700 feet worth of intestines.

20. The stomach can hold up to 50 fluid ounces.

The stomach may not be tennis court size, but it can hold around 16 to 50 fluid ounces. It's interesting to note that a Trenta size at Starbucks is 31 fluid ounces, which is more than many adult stomachs can technically hold.

21. The neurotransmitter serotonin can be found in the gut.

Our gut contains 95 percent of the neurotransmitter serotonin. In fact, the gut, with its 100 million neurons, is so important to mood that it’s sometimes called the “second brain.” Medications that affect serotonin will often also cause GI issues.

22. The skin is the largest organ.

The skin is considered an organ and it's the body's largest one. An adult may have 22-square feet of skin on their body. Basically that means your skin could comfortably stretch across half the floor of the typical bathroom.

23. The skin makes up a large part of your body weight.

Fifteen percent of your total body weight, to be exact.

24. The ovaries are in communication with the brain.

It was once believed that the ovaries and uterus sort of sat dormant until they were needed, but the ovaries actually communicate with the brain in ways we’re just learning about. The hypothalamus and ovaries work together to make sure that the levels of hormones in the ovaries, like estrogen and progesterone, are where they need to be.

25. Humans are covered in stripes.

The human body is covered in stripes called Blaschko’s Lines, which are typically invisible. They’re cellular relics of our development from a single cell to a fully formed human.

26. Humans glow, but our eyes aren't able to detect it.

Humans glow, but it’s just around 1000 times weaker than our eyes can detect. Every animal that has metabolic reactions glows because in that process, photons get emitted, causing light. In 2009, a study was published in which a camera captured the bioluminescence of five men. According to that study, our upper body lights up the strongest. And the glow is on a cycle; when we’re on a normal sleep schedule, our bioluminescence is at its strongest at about 4 p.m.
