5 Surprising Facts About Nature, Fire, and Everyday Wonders

1. What Is a Sabra Fruit?
The sabra fruit also called sabres, is sweet on the inside but covered with sharp thorns on the outside. Its thick skin and spiky surface once made it a natural fence in farm areas, keeping people and animals out. The plant is called “sabra” because it stores lots of water to survive long dry periods.

2. How Does Limescale Form?
The white buildup we see in sinks, kettles, and showers comes from limestone rocks. Rainwater slowly dissolves these rocks, and the minerals stay in the water. When the water heats up, those minerals harden and leave limescale behind.

3. What Is the Archimedes Screw?
Long ago, a Greek inventor named Archimedes created a simple tool shaped like a screw. It was used to lift water from wells or remove it from boats. You’d spin the screw, and water would rise from a lower place to a higher one.

4. How Were Stain-Resistant Fabrics Invented?
Clothes that resist stains and water were inspired by nature. Scientists looked at the lotus plant, which stays clean even in muddy water. Its leaves naturally repel dirt and liquids and that idea helped people design fabrics that do the same.

5. What Is Fire, Really?
Fire is what we see when gases are released during burning. When something burns, it releases energy in the form of heat and light. That glowing light is the flame and it’s the result of hot gases shining as they rise.

Even everyday things hold hidden wonders. There’s so much to learn just by looking a little closer!
