Have you ever felt sick to your stomach after eating? There can be many reasons. One possible reason is eating two foods that digest at different speeds. For example, if you eat watermelon and meat at the same time, it can cause problems in your stomach. Watermelon is digested in less than 30 minutes. But meat takes 3 to 5 hours. You might think watermelon would leave your stomach first. But that’s not how it works. When you eat two foods together, they leave together. So the watermelon has to wait. While waiting, it can go bad in your stomach. Think of a highway. If a slow car is in front, fast cars must wait. It’s the same with food. Fast-digesting foods like fruit should not be eaten with slow ones. The best way to eat fruit is to eat it alone, not with other foods during meals. That helps your stomach feel better and work well.

Walter Hunt was an American inventor a long time ago. His name may not be well-known, but he made something very useful! One day, he was sitting at his table where he made little inventions. He was thinking about his debt. He owed his friend $15 and didn’t know how to pay it back. Since he was feeling nervous, he twisted a piece of wire on the table. Suddenly, a great idea came to him. He made a pin with a bent wire to cover the sharp end. It was a special kind of pin that didn’t hurt your fingers. Walter’s safety pin was perfect from the start. That’s why it has stayed the same for over 150 years. A great idea never gets old!

Did you know some jellyfish have a way to live forever? It sounds like a story from science fiction, but it’s real! When these jellyfish get old or sick, they don’t just die. They do something amazing. They turn back into babies! It’s like pressing a reset button on life. Then the baby jellyfish grow up again. And it starts all over. It’s like hearing your favorite song play again and again. But not all jellyfish can do this. Only one kind — the scarlet jellyfish—has this special power. It can go from old to young many times. Scientists are studying this jellyfish to find out its secret. They hope it might help people live much longer than now.
