Ready for another round of SmartEQ, where your questions become my homework. Today I'm answering questions about hair, wasps, stars and fish that don't get squished by all that water pressure in the ocean. Oh boy, let's get smarting. Our first question comes from Cora in Pittsburgh who asks what makes people have curly hair, wavy hair, or straight hair? Excellent question. The answer mostly comes down to the shape of your hair follicles. Hair follicles are tiny little pockets in your skin where each strand of hair grows. If a follicle is very round, the hair tends to grow straight. If the follicle is slightly oval shaped, the hair often grows wavy, and if the follicle is more curved or flattened, the hair is more likely to grow curly. Your Genes the instructions you inherit from your parents help determine the shape of your follicles. The shape of the hair strand itself matters too. Curly hairs tend to twist as they grow, while straight hairs grow more evenly. So whether your hair is straight, wavy, curly or somewhere in between, you can thank your follicles and your genes. Our next question comes from Jacob, a super polite young man from Toronto, Ontario, Canada who asks how do wasps make super duper strong nests? Great question. In case you didn't know, wasps are amazing builders. Many kinds of wasps make their nests out of something that's basically insect made paper. Here's how the wasps chew bits of wood from trees, fences and branches. They mix those wood fibers with their saliva, you know, wasp spit. The result becomes a soft, papery pulp. The wasps then spread that material into thin layers that dry and harden. By adding layer after layer, they create nests that are surprisingly strong and lightweight. Some wasp nests can survive heavy rain, strong winds, and months of outdoor weather. Our third question comes from Sophia in Issaquah, Washington, who asks why do people sing in the shower? Another great question. One reason is that bathrooms are full of hard surfaces like tile, mirrors and porcelain. When sound bounces off those surfaces, it creates echoes and reverberations, also known as reverb, that make your voice sound fuller and richer. In other words, the bathroom is kind of like a tiny concert hall. Another factor is people tend to feel relaxed while showering or taking a bath. You're warm, comfortable, and usually not distracted by school, work or chores. When people are relaxed and happy, they're more likely to sing, hum, whistle, or make up silly songs. So if you've ever felt like a rock or pop star while shampooing your hair, you are definitely not alone. Okay, three cool questions asked and three cool questions answered. But we've got more curious questions on the way right after this quick break and a word from our sponsors. Decal.

hey smarty pants, Quick question. Would it be cool to slice flying fruit out of the air like a ninja? I'm hearing a lot of yeses. Well, last weekend I was actually doing it in my living room, just me chopping watermelons and pineapples out of mid air while my dinner was bubbling on the stove. How Nex Playground Nex Playground is a kid focused game system where your body is the controller, no joystick, no buttons. The player playground sees your moves and you're in the game. I've been crushing fruit Ninja and there's also Bluey and Ninja Turtles games and an Avatar Earth Rumble tournament where I got to bend rocks. Dance games, sports games, over 50 games. Once you Add play pass Smarty parents, here's the part for you. Playground is built kid safe. No ads, no in app purchases, no mature content, no online chat with strangers. Just your smarty pants moving their body, having a blast playing games that you can actually feel good about. It's the screen time solution that's also exercise, which means everyone wins. Check out next playground@nexplayground.com that's nexplayground.com Trust me, your living room is about to get a lot more interesting. Hey, who smarted families trusty here. You know me, always here with the facts, the stories, the wild science. And today I have an extra special book series to introduce you to. Meet the investigators Mango and Brash are two alligator secret agents who travel through the city sewers to fight crime and solve the most wonderfully weird mysteries. If you love the puns and silly humor we throw at you on every episode of who's Smarted? You're gonna feel right at home. It's basically who Smarted Energy in graphic novel form. Over 4 million copies have been sold worldwide. 4 million. Now there's nine books in the series, a special edition, and a spinoff. So if you plow through books, this is basically a gift. And the newest case just dropped. Investigators, Whether or Not by John Patrick Greene where the city's water supply has been replaced with milk. The rain is turning green and monkey scientists are causing chaos. So grab your copy of Investigators, whether or not at your local bookstore, library, or online today. Now back to Smarty Q. Our next question comes from Amelia, who asks, how does the water we use for drinking and bathing get cleaned before it comes out of our faucet? Oh, we're still in the bathroom. Great question. Before water reaches your home, it usually goes through a water treatment plant. First, water is collected from sources like rivers, lakes, reservoirs, or underground aquifers. Then it goes through several cleaning steps. Large screens remove sticks, leaves, and other large debris. Tiny particles are clumped together so they can be removed. The water is then filtered through special materials such as sand and gravel. And finally, it's disinfected to kill harmful germs and bacteria. After that, the clean water travels through miles and miles of underground pipes until it reaches your faucet. So every time you turn on the tap, you're using water that has gone through a pretty impressive and extensive cleaning process. Our next question comes from Julian in Wayne, Pennsylvania, who asks, why are stars different sizes? How do they grow or die and do some shrink? Wow, that is one big cosmic question. Stars come in different sizes because they begin with different amounts of gas. You see, stars form inside giant clouds of hydrogen gas. Some clouds contain enough material to create small stars, while others create stars hundreds of times larger than our sun. As stars age, they change size. Some stars actually expand and become enormous red giants. Others eventually run out of fuel and collapse inward. Smaller stars may end their lives as dense objects called white dwarfs, while huge stars can explode in gigantic events called supernovas. And yes, some stars do shrink dramatically near the end of their lives. Stars are constantly changing throughout their incredibly long lifetimes, some living for billions of years before finally fading away. Okay, we're down to our final question, and it involves a baffling underwater mystery. We'll find out what it is right after this quick ad break and a word from our sponsors. Hey, Smarty parents. I have to tell you about something that's genuinely changed my life. I've been using the Skylight Calendar for about three months now, and I am not exaggerating when I say it has completely transformed how we organize our household. Now, you've probably seen this thing all over social media, and for good reason. Setting it up was so easy. Within minutes, it was pulling in everybody's schedules into one place. We're talking calendars to do, lists, tracking systems. Plus we can add recipes, notes. It's awesome. Everything's in one screen. Done. I love this thing so much that I'm already planning to give it as gifts to friends. That's how good it is. And for families with kids like you, the tasks feature turns chores and routines into something that's actually fun and rewarding for the kids. No more. I didn't know I had to do that. It syncs with Google Calendar, Apple Calendar, Outlook, and more. And if you're not 100% thrilled, you have four full months to return it for a full refund, no questions asked. Families are better when they're working together. Right now, Skylight is offering our listeners $30 off their 15 inch calendars by going to myskylight.com smarted go to myskylight.com smartED for $30 off your 15 inch calendar.

We're finally free. Wait, who said that milk can't stop pickles from coming alive. Now back to Smarty Q. Our final question comes from Luna in Wisconsin and California. Who asks if water pressure is so powerful, how is it that fish don't get crushed, especially since their bodies are much more delicate than metal? Excellent question, Luna. The answer is fish are mostly made of water themselves. Water doesn't compress very much under pressure, so the water inside a fish helps balance the water pressure outside the fish. Think of it this way. If pressure is pushing equally on all sides of an object, that object doesn't necessarily get squished. Many deep sea fish are also specially adapted for life under tremendous pressure. Their bodies don't often contain large air filled spaces that could collapse. Some deep sea fish live thousands of feet below the surface under pressures that would easily crush a human or even a submarine. So while fish may look delicate, they're perfectly designed for the watery world they live in. That brings us to the end of another episode of Smarty Q. If you've got a cool and curious question that you'd like me to answer, have a grown up help you email me at whose smarted@whosmarted.com and I'll happily add it to my Smarty Q list. Until next time, keep on smarting, smarty pants.
