📈 What are stocks and bonds?

Stocks and bonds are like special tickets that grown-ups use to help companies and governments. 🎟️

When you buy a stock, it means you own a tiny piece of a company, like having a little piece of a big pizza! 🍕 If the company does well, your piece might become more valuable.

When you buy a bond, it's like lending money to a company or government. They promise to pay you back later with a little extra, like when you lend a toy to a friend and they give you a sticker in return! 🏛️

📈 How does the stock market work?

The stock market is like a big shop where people buy and sell tiny pieces of companies called stocks or shares. 🏪💼

When you buy a stock, you own a little part of that company! If the company does well, your stock might grow in value, just like a plant grows when you water it. 🌱💰

People trade stocks to make money, but sometimes they lose money too. It's like trading toys with friends—sometimes you get a cool toy, and sometimes you don't!

🦅 Why can’t people fly like birds?

People can't fly like birds because we don't have wings! 🦅 Birds have special wings and light bodies that help them soar in the sky. We have arms and legs, which are great for walking, running, and playing, but not for flying. 🌈

Also, birds have strong muscles to flap their wings very fast. Our arms aren't strong enough to lift us up like that. But don’t worry—people invented airplanes to fly high in the sky! ✈️

🔋 How do batteries and accumulators work?

Batteries are like tiny power boxes! 🔋 They store energy and give it to your toys, remote controls, and other devices when they need it. Inside a battery, there are special chemicals that make electricity when they react together. When the battery is used up, the chemicals can't make electricity anymore.

Rechargeable batteries (accumulators) are special because you can fill them up with energy again, just like filling a water bottle! ⚡

🎈 Why do balloons fly?

Balloons fly because they are filled with something very light, like helium or hot air! 🌬️

When a balloon is filled with helium, it's lighter than the air around it, so it floats up, up, up into the sky! 🎈

Just like how a bubble floats in the air, balloons do the same!

🎈 How did airships (dirigibles) fly?

Airships are like big floating balloons! 🎈 They have a special gas inside that makes them lighter than air, so they can float in the sky. They also have engines to move forward and big fins to help steer. Think of them like giant, slow-moving airplanes that don’t need wings!

Fun fact: The biggest airship ever was as long as three football fields! ⚽⚽⚽

🏃 Which animal is the fastest?

The fastest animal in the world is the cheetah! 🐆 It can run as fast as a car on the highway—up to 70 miles per hour (112 km/h)! That's faster than any other animal on land.

Cheetahs have long legs and a flexible spine that helps them stretch really far when they run. They also have special claws that grip the ground like running shoes!

👕 How is clothing made?

Clothes are made from special materials called fabric! 🧵 First, people grow plants like cotton or get wool from sheep. Then, they spin these into soft threads. The threads are woven or knitted together to make fabric. Finally, the fabric is cut and sewn into clothes like shirts and pants! 👖

Did you know? Some clothes have buttons, zippers, or even sparkly decorations! ✨

🎮 How are computer games created?

Computer games are like magic stories that people create! 🎮✨ First, someone thinks of a fun idea, like a game about jumping dinosaurs or racing cars. Then, artists draw colorful pictures, and programmers write special codes to make everything move and work. Finally, they test the game to make sure it's super fun to play!

Imagine building a toy castle—first, you plan it, then you build it, and finally, you play with it! That's how games are made too!

🍶 What is porcelain?

Porcelain is a special kind of shiny, white material that is used to make beautiful cups, plates, and toys! 🎨✨ It feels smooth and is very delicate, so you have to be careful with it.

People make porcelain from a special type of clay called kaolin. When it's heated in a very hot oven, it becomes hard and shiny like glass! 🏺
