The royal family has plenty of strange traditions and regulations. From the most unusual etiquette rules to the way they dress or how they celebrate holidays. For example, did you know that the Queen celebrates her Birthday twice a year: on April 21st and June 12th? Does she get twice the number of gifts as well? Let's find out!

No one knows royal protocol like Her Majesty. Queen Elizabeth II is England's longest reigning ruler. She enjoys numerous royal privileges and aspects of power. Among her many privileges, Queen Elizabeth doesn’t have to face the stress of having to pass a tricky driving test. She is the only person allowed to sit behind the wheel in Britain without a driver’s license. How's it possible?

I bet you can recognize the Queen's style from dozens of looks. She always has a hat on, a black handbag matching her shoes and an outfit of some bright color. But did you know that the color of the look isn't random at all? When it comes to royal style, everything is intentional. Let's find out what the choice of color for the Queen's 'look of the day' means.

Can airplanes safely operate with one engine? What's the fastest commercial airplane ever produced? How do planes detect other aircraft? Everything connected with planes is well-planned and thought out. Perhaps it’s the main reason why a plane is the safest way to travel. Today, we'll answer the most popular questions about airplanes. Do you know, for example, why on airplanes, the captain sits in the left seat, and the co-pilot - in the right? Well, the reasons for that are historical. One theory is related to horses, another one involves trains. These days, though, both seats have full control of the plane. And there are no regulations that would specify which seat the captain and the co-pilot should occupy. (Maybe it’s just rock-paper-scissors?) The world of aviation is fascinating, and we’d like to share with you the most interesting facts about planes and flying.

Elections are one of the most awaited events in a country. And picking the most intelligent and responsible representative is definitely a must. Most of us have our very own expectations, but seeing a cat or a dog on your ballot isn’t one of them. Non-human electoral candidates: this is the term coined for animals who run for a specific office. There are, surprisingly, a lot of amazing cases all over the world. In case you’re wondering why and how this happened, the answer would be either a kind of protest or purely for entertainment purposes. So what would happen if a dog or cat has been elected as a Mayor?

The human body is one of the most complicated and trickiest living forms on Earth. Even though we have a lot in common, there´re certain unique features that make each human body special. Here are some interesting features that make it special. For example, did you know that around 6% of people can rapidly shake their eyes back and forth? Sounds like a great party trick. Wanna take a look at it?

When you think about a planet with lots of rings, Saturn comes to mind. But there's another planet out there that has rings 200 times bigger! Astronomers are still investigating it and say it could be a brown dwarf - something between a large planet and a full-fledged star. What makes this planet special and how did those huge rings appear around it?

When you're thirsty, you go to the supermarket, grab a bottle of any water and drink it. Wait... there's a huge mistake here: you shouldn't grab ANY water from the shelf. The first thing to look at when you pick a bottle of water is the bottom. Turn it over and look for the recycle symbol with a number inside of it. Those marks might seem meaningless but actually have plenty of information. I'm gonna tell you which marks indicate that the plastic this bottle is made of will most likely already be releasing dangerous chemicals. Those chemicals will penetrate into your drinks or food. You'll also find here 12 other things you shouldn't buy and why...

We seem to think we know pretty much all there is to know about our Earth that nothing can surprise us at this point. You’ll be amazed when you find out how much you have yet to learn about our home planet: let’s start with 10 little-known earthly facts. You might know that it’s called “the blue planet”, but did you know that scientists say Earth was originally a different color? Or that the Moon isn’t Earth’s only satellite? The magnetic field is vital for Earth because it protects the planet from the impact of solar winds. We think of our planet’s magnetic field as something constant and stable, but the truth is that it’s changing. James Ross, an explorer and British naval officer, pinpointed the northern magnetic pole for the first time in 1831. In 1904, Roald Amundsen, a polar regions explorer from Norway, reached the north magnetic pole again and was surprised to find that it had shifted 31 miles since Ross's discovery. Earth, despite common belief, isn't perfectly round. It’s more like a squashed sphere. So its mass is irregular and differs in various places, which causes “wobbles” of gravity in different areas of the planet. A smaller celestial body about 750 miles wide orbited Earth like a second moon. It most likely crashed into our main satellite later on. Scientists also don't rule out the probability that one day Earth will get another satellite. If all the gold found inside the Earth could be extracted, it would be enough to cover the entire surface of the planet in a 2-foot layer of gold. And if we gave everyone an equal piece, each one of Earth’s inhabitants would get 9 pounds of this treasure. Magma lurking below the surface of crater lakes emits carbon dioxide into the waters of the lakes. This carbon dioxide builds up in a thick layer at the bottom of the lakes until pressure gives way, and it’s released in an explosion.

Planet Earth is amazing: we keep investigating it and yet we learn more and more amazing facts about our home each year. Have you ever wondered, what'd happen if Earth grew bigger every year, like any living organism? Would it turn into a giant planet and how big could it get? Let's take a look at some amazing things that could happen in space.
