How Do Boats Float on Water?
It might seem strange, but heavy boats can float! While gravity tries to pull the boat down, the water pushes it up. This push is called buoyancy. If something is denser than water, it sinks. But when it’s big and wide like most ships, it floats because it gets more support from the water.
Which Animal Has a Natural Dust Filter?
The saiga is a type of antelope that lives in Central Asia. It has a funny-looking nose, but it’s really helpful. This nose filters out desert dust and also warms up the cold winter air so the saiga can breathe more comfortably.
What Did a Bird Teach a Train Engineer?
The kingfisher bird dives into water so smoothly that it barely makes a splash. A Japanese train engineer noticed this and used the bird’s beak shape to redesign the front of high-speed trains. Thanks to that design, the trains move more quietly and smoothly, especially when leaving tunnels.
Can a Fish Really Eat a Cow in Minutes?
No, not really! Piranhas live in South America and are known for their sharp teeth. But they don’t go around eating cows. Usually, they take just one bite of fish or animals in the water.

Is There a Flower That Smells Like Chocolate?

Why Is the Keyboard Set Up That Way?
You might wonder why the letters on your keyboard are in such a strange order. It’s called the QWERTY layout, named after the first six letters on the top row. It was designed by Christopher Sholes for old typewriters. The idea was to slow down fast typing so the machine wouldn’t jam. Even though we have modern keyboards now, most people still use this same setup!
