Today's Wonder of the Day was inspired by Bob. Bob Wonders, " How can flamingos balance with one leg? " Thanks for WONDERing with us, Bob!

We were getting ready to watch the sun set over the Wonderopolis waterfront the other day when we overheard an interesting conversation between a sea gull and a flamingo:

Sea Gull: Hey there! My name's Babs. What's yours?

Flamingo: Nice to meet you, Babs. My name's Frank. I don't think I've ever seen you here before.

Sea Gull: I'm new to the area. If you don't mind me asking, there's something I've always wanted to know about flamingos.

Flamingo: Oh year? What's that? Why we're pink?

Sea Gull: No, I know you're pink because of what you eat. I've always WONDERed why you stand on one leg when you sleep.

Flamingo: Ha! That's a funny story. A flamingo did it once and it made the humans freak out. He posted a video on FlamingoBook and it went viral. Now all the flamingos do it just to the humans!

We believe that Frank was just pulling Babs' leg, but their conversation did make us WONDER about exactly why - and how - flamingos stand on one leg while they sleep.

Standing on one leg is not - or - for human beings to do for any length of time. Yet, flamingos seem to do it with ease for long periods of time with little or no .

Scientists who have studied flamingos have this for a long time. Over the years, they even several about how and why flamingos stand on one leg when they sleep.

Some think that flamingos stand on one leg to dry it off from time to time, since they spend so much time in the water. Others think they stand on one leg because they only turn off one side of their brains when they sleep.

More popular concentrate on of standing on one leg. For example, some scientists believe standing on one leg conserves energy and reduces on the heart, since the heart only has to pump blood all the way down one leg.

Others think it helps flamingos to body temperature. Standing in cold water all day can make it difficult to keep body temperature up where it belongs. Standing on one leg reduces the amount of heat lost to the water, thereby helping to control body temperature.

Another popular theory holds that standing on one leg could be a form of camouflage. From the point of view of fish swimming below the water, a flamingo standing on one leg could resemble a or small tree.

For years, all scientists have had are these . Recently, however, scientists studying flamingos may have made a breakthrough in understanding this peculiar .

Professor Young-Hui Chang of the Georgia Institute of Technology and Lena Ting of Emory University studied the bodies of dead flamingos to learn more about their anatomy. In the process, they discovered it takes less for a flamingo to stand on one leg than it does on two.

When you see a long flamingo leg, you're actually just seeing the calf, ankle, and foot. A flamingo's knee is hidden beneath its feathers where you'd imagine its hip would be. The ankle is where you'd expect the knee to be, and it does something unusual. A flamingo's ankle joint snaps shut, locking the foot-to-leg connection in place.

When studying a flamingo corpse, researchers were able to balance it on one leg because its joints naturally aligned so that one leg was positioned beneath the of the body. Since this could be done with a dead flamingo, researchers concluded that standing on one leg couldn't require any muscle activity at all in live flamingos.

So, unlike humans who have trouble standing on one leg and can only do so for a short time with great muscle , flamingos can stand on one leg without any muscle activity at all. Isn't nature interesting ? Who would've thought that standing on one leg could actually be easier than standing on two legs?

Today's Wonder of the Day was inspired by Katherine. Katherine Wonders, " How does your brain tell you what you like to eat? " Thanks for WONDERing with us, Katherine!

Just the other day we were walking past the Wonderopolis gardens when we overheard an interesting conversation between a couple of rabbits:

Rabbit 1: Hey Roger! What's up with all these carrots?

Rabbit 2: I don't know, Eddie. I like to hang out here a lot. Every time the humans see me, they throw carrots at me.

Rabbit 1: Eww! Why do they do that? I hate carrots!

Rabbit 2: Me, too! They bring sandwiches, hot dogs, cookies, and chips on picnics, but do they ever share any of that food? No way! I'd do a for a cheeseburger right now.

Rabbit 1: Mmm...a cheeseburger does sound good right now. Want to go to Old MacDonald's for ?

Rabbit 2: Let's do it! Maybe we can all these carrots for some French fries!

We were by the rabbits' conversation, since we had always that all rabbits loved carrots. In fact, their conversation made us start WONDERing about the foods we eat. Why don't we all like the same foods?

If you've ever been out to eat at a restaurant with your family, you've probably that everyone doesn't the same meal. In fact, if there are five people at your table, there are probably five different meals ordered.

Some foods, such as ice cream and pizza, seem to to most, if not all, people. Other foods, like broccoli and spinach, seem to be an taste that relatively few people have . What drives these differences in our tastes?

Scientists who have studied foods and our sense of taste have identified a variety of factors that lead to our likes and dislikes when it comes to foods. First, we're not all created equally when it comes to taste buds. The number of bumps on our tongues (called papillae) that contain taste buds varies from one person to the next.

People with many papillae are known as "supertasters." They can find flavors overwhelming and often foods that are mild rather than . Those who have a low papillae are called "subtasters," and they're the people who tend to like food and hot sauce on everything.

Our sense of taste depends upon more than just the number of taste buds, though. It also depends upon our taste buds' ability to detect the wide variety of chemicals that can the signals that help our brains interpret the five different tastes: sweet, sour, salty, bitter, and savory.

Scientists believe our sense of taste definitely has a genetic component. For example, researchers have identified a range of 20-40 genes they believe influence how our brains and taste buds sense bitter tastes.

Humans appear to be born with a natural love of sweet flavors and an aversion to bitter and sour flavors. Scientists believe these genetic predispositions have evolutionary roots, since sweet flavors would likely come from good food sources, such as fruits, while bitter and sour flavors would often come from dangerous plants that should be avoided.

Experience also plays a role as we grow up. For example, babies often tend to like foods their mothers ate before they were born. Children exposed to a wide variety of foods when young also tend to like more foods than those fed a limited diet.

and culture can also play roles in our tastes. Women tend to crave sweets, while men often salty foods. Bitter or foods may be more popular if you're part of a culture that celebrates those foods and eats them regularly.

Finally, scientists also know that texture plays a big role in many people's likes and dislikes. They can't really explain why yet, but it's clear that some people simply don't like certain textures - slimy, chewy, gritty, creamy, or stringy - regardless of flavor.

Each fall, the leaves of the trees begin to turn colors, creating a beautiful backdrop that only nature can provide. As the leaves begin to fall and temperatures begin to drop, you start seeing typical fall decorations appear in preparation for Halloween and Thanksgiving.

Along with scarecrows, gourds, cornucopias, and black cats, you're also likely to see a lot of large orange objects. What are we talking about? Pumpkins, of course! All you have to do is look around to find jack-o'-lanterns decorating the front porches of houses everywhere.

One popular party game that often makes an appearance in the fall is for apples. It can be so much fun to tie your hands behind your back and attempt to retrieve a floating apple from a large tub of water.

Know what would be even more fun? for pumpkins! But can you even do that? Many pumpkins are the size of watermelons. Surely, those big pumpkins wouldn't ! Or would they?

If you've ever dipped a in the bathtub or thrown one into a lake, you know for a fact what might surprise many people: pumpkins do indeed ! But how is that possible? How can they not be too heavy to ?

It's not all that surprising if you think about it another way: do you ? Are you heavier than a ? Both of those answers are a resounding yes! So what's the key to floating anyway?

To learn why we - and pumpkins! - , we only need to turn to science. Particularly, we just need to consult an ancient Greek scientist named Archimedes. Hundreds of years ago, while taking a bath, he discovered the secret to floating and jumped naked from the tub to run the streets, shouting "!" and explaining what he learned to anyone who would listen.

Basically, Archimedes' (as it came to be known) holds that an object immersed in a fluid will be buoyed up by a equal to the weight of the fluid it displaces. Simple enough, right? Don't worry! You're not the only one who needs that clarified a bit more.

Think of it this way: if you place a into a bathtub full of water, some of the water has to get out of the way to make room for the . The water that gets out of the way is from where it used to be.

Where does the water go? There's only one place for it to go: upward. That's why the water level rises when you put the into the bathtub. But gravity is still pulling that water back down, and it wants to return to where it came from.

The only problem is that there's now a where the water used to be. Fortunately, water has a of about 62.4 pounds per . That means it can push back on the with about 60 pounds of .

Since the is less dense than the water, the water is able to push the up quite a bit, so that it floats. If the were denser than water, the water would not be able to generate enough upward . In that case, the would .

Based upon this , we can conclude that any object less dense than water will . On the other hand, objects denser than water will . Pumpkins, although large, aren't very dense because they are mainly hollow inside. Given their large size, though, they displace a large amount of water. With a mainly hollow , it's easy for a to weigh less than the large amount of water it displaces!

Today's Wonder of the Day was inspired by Isabella. Isabella Wonders, " Why do we all have different handwriting? " Thanks for WONDERing with us, Isabella!

Want to try a and fun experiment ? Ask a few friends or family members to join you in a simple : write out the first couple of lines of a or poem. When you're all finished, set the papers in a row and compare them.

Does everyone's handwriting look the same? Or is it easy to distinguish each person's handwriting from the others?

If you and your friends and family members are like most people, then we bet you have several handwriting samples that all look . In fact, the handwriting samples might remarkably from one person to the next.

So does everyone have different handwriting? Is handwriting like your fingerprints or voice? Not exactly! After all, you're born with a voice and fingerprints, but you don't learn how to write until several years later.

Although handwriting hasn't been subjected to scientific study as frequently as fingerprints have, most people do believe that each individual's handwriting is . Why is that, though?

To be able to communicate , all letters should look the same, right? In school, when you learn to write, all students are usually shown the same examples of letters. So why doesn't everyone's handwriting look the same then?

If you think about handwriting, you'll quickly that it's a complicated that involves parts of the body at once. Your brain must the letters you want to write. Your nerves must communicate those intentions to the muscles in your hands and arms.

At the same time, your eyes watch the letters as you write them, constantly monitoring their shapes and alerting your brain to corrections that need to be made. As if all that wasn't enough, your handwriting can also be affected by a variety of environmental factors, such as the temperature of the room, your level, time constraints, and your overall .

When you put all those factors together, it's no surprise that each person's handwriting turns out differently from others. In fact, an individual's handwriting isn't necessarily always the same, since it can based upon any of the factors mentioned previously. Even twins have different handwriting!

Some people practice graphology, which is the study and analysis of handwriting. The most common graphology technique, known as graphoanalysis, was developed by Milton Newman Bunker in the early 1900s.

Graphoanalysis involves studying and analyzing the stroke shape of letters. Some graphologists believe that they can determine certain personality and character traits of people based upon their handwriting.

Graphology remains controversial today. Some characterize it as a pseudoscience , since its methods don't always conform to traditional scientific methodologies. Others debate how accurate it is at determining personality traits.

Even though the debate about graphology is not likely to end any time soon, scientists are still studying handwriting, seeking to determine scientifically how it is. Their findings may impact, for example, whether or not handwriting can be reliably used as evidence in court proceedings.

For example, scientists at the State University of New York at Buffalo have published a study about handwriting in the Journal of Forensic Sciences. Their study used a computer running handwriting recognition software to analyze 1,500 samples objectively based upon 11 different features. Their study concluded that all 1,500 samples were indeed !

This is just some of what the Australian Bat Clinic does to care for orphaned baby bats: feeding, grooming, attending to their medical needs, and making them feel warm and safe by wrapping them like a ridiculously cute baby bat burrito. From Wakaleo:

When a bat mother dies, often their young are still attached and will not survive without the right care. Bat carers play a vital role in not only retrieving suffering bats, but rehabilitating them until they can be released back into the wild. When baby bats first enter rehabilitation it can be traumatising for them as they have just been separated from their mothers to which they have formed strong bonds. Bat carers have to ensure that the baby bats not only are well fed, but that they are nurtured and feel safe in their temporary new home. Providing affection the bats is a necessity.

The teats represent their mother's nipple, and this makes them feel more comfortable, as does the security of the blankets which they are often snuggly wrapped in.

When the bats grow old enough, they're returned to nature so that they can contribute to Australia's embattled flying fox habitats. In this 2013 video, we can see how these babies flourish as they reach maturity, soon to be transitioned into soft release exhibits before returning to the wild:

If you find a bat, contact a local bat rescuer. For their safety and yours, bats should not be handled by anyone other than a trained bat caregiver.
