SUMMARY: - Right before take-off, you should go to "Settings" on your smartphone and choose the Airplane Mode. Then, you re-enable Bluetooth by choosing "On" in your Bluetooth settings. - If your AirPods are running low on battery, you can use just one earbud at a time! Keep one of them in the charging case, and listen to music or whatnot through the other. - You can find out who's calling you without having to look at the screen of your phone! Choose "Phone" in your Settings, and tap "Announce Calls."  - Unfortunately, AirPods aren't water-resistant. So don’t shower with them. - The "disconnection problem" may occur because of the dust and dirt stuck inside. - You can set up "Find My AirPods" in the "Find My iPhone" application so that you never have to rummage around your place trying to locate them.  - You can still use your AirPods even if your phone wasn't produced by Apple! Examine the back of the charging case - see that small, flush button? You can use it to pair your earbuds to an Android device without any problems!  - If you have second-generation AirPods, you can chat with them. Well, not with them, obviously, but with Siri.  - You can change the name of your AirPods! Just choose "Bluetooth" in your phone's Settings, find the blue letter "i" with a circle around it near "AirPods," and tap it. You'll see the box saying "name" - that's where you can type any name that fits your earbuds the best.  - If your AirPods are inside the case, and the lid is open, the green light means that your AirPods are fully charged, and amber indicates that less than one full charge remains.

When you're getting ready for a flight, two main things you might be worried about is how to stuff all your travel essentials into your modest-sized suitcase and how to get through the security screening as fast as possible. Interestingly, both of these things depend on how carefully and thoughtfully you pack your carry-on and checked luggage.  Do you know, for example, that if you don't charge your laptop before the flight, it may be confiscated? Packing an electric brush in your carry-on may land you in trouble at the security check.

Space fans, rejoice! The James Webb Space Telescope has discovered something absolutely amazing – a star-planet hybrid with very strange clouds. This bizarre world, called VHS 1256 b, is actually a brown dwarf. Those are bigger than planets but too small to classify as stars. They emit some light of their own and are quite hot. Is the new discovery dangerous for us?

You’re at home, scrolling through the feed, watching some videos, when the power suddenly goes out! No big deal, the phone’s still working until the battery runs out. But sooner or later, you’ll wonder… why won’t the toilet flush with the electricity out? It’s not like commodes are plugged into an outlet right there in the bathroom wall. When you push the flush handle, a large flow of water rushes from the tank into the bowl. It works just by the force of gravity if your house has a gravity-fed waste removal system.

While gravity is always at our service (unless your toilet’s in space), there’s one problem with no power: the tank doesn’t get filled! Actually, the way your plumbing works depends on your water source and where you live. For example, the plumbing system in high-rises is so complicated, there are even legends about it. One of them says, if all the toilets were flushed at the same time, it could take down the building! Let's figure out how a toilet works and what kind of toilet myths there are.

If we managed to swap time and space, the whole Universe would turn into a chaotic collage of many historical events. Imagine drawing a light bulb on a sheet of paper. Then grab one more sheet and draw how it lit up. Right now, it’s just a small circle of light. Another sheet — the circle of light is growing. We see how over time, the light has grown from a small dot to a large circle, and it looks like a cone - a light cone. So, what will happen if this cone approaches a black hole?

During the recent years, scientists made two breakthrough discoveries about our universe. Thanks to new technologies, we’ve looked into the distant past... and we’ve learned something that can change our understanding of the universe forever. We unveiled the first color image from the James Webb Space Telescope. It’s a mind-bending photo capturing thousands of ancient galaxies. This "oldest documented light in the history of the Universe" dates back over 13 billion years. But what does it mean to us?

The Wild Wild West has taken over people’s imagination since Hollywood created its own version of what it was like to live the cowboy life. This included crowded Saloons, bounty hunters, and wearing a lot of leather clothing in extremely hot weather. Of course, Hollywood’s version of the West was more fictional than it was real. The day-to-day lives of the real American cowboys were a little less eventful than that. But it was still full of fascinating stories.

For a long time, scientists believed that Mars was indeed a "Red Planet". When it's far away from us, Mars appears as a tiny, twinkling red dot in the night sky, like a glowing ember in a sea of stars. But as it gets closer to Earth, it becomes more visible. So its reddish hue becomes more apparent. But is it really red, and what other secrets is it hiding?

Lost in the woods. I’d never thought it would happen to me, but here I was, standing all alone in the grove not far from my home, watching the last rays of the sun disappearing. And as they fell on the ground beneath my feet, I saw something that made my heart jump to my throat and stay there. Fingers. Five of them, black and gnarled, with bluish-gray nails, poking from underneath some stump nearby. I couldn’t scream, but thankfully, my legs turned me around and carried me out of the woods. I didn’t care where I’d end up, I just needed to get away.

Luckily, by some wild chance, I ran in the correct direction, and soon saw the opening in the trees and a familiar glade. In some 15 minutes, I was home, still shaking. I took a cup of tea and turned on my phone to search for answers if there were any. It didn’t take me long to realize, with relief, that what I saw was Xylaria polymorpha — a species of mushrooms otherwise known as Dead Man’s Fingers. By the way, it turned out there are many weird and scary plants in the world. Here's a compilation of the spookiest ones.

How heavy can a human get? When the heaviest man in the world was just 12 years old, he already weighed 294 pounds. By the time he turned 22, he weighed 500 pounds! It took over 12 people and a custom stretcher to move him. And he's not the only unique person: let's look at the guy who had hiccups for 68 years, slept for 11 days straight, or was taller than the tallest NBA player in history.
