Okay, kiddo, have you ever heard of fish? They live in water and people like to eat them because they taste very good. But some people don't like the idea of catching fish from the ocean because it can harm the environment and the fish population. That's why some really smart people are trying to make fish without actually catching them.
They call it "finless foods." It's kind of like making a cake or cookies, but instead of using flour and sugar, they use cells from a real fish. These cells are kind of like building blocks that can make more cells and grow bigger.
Scientists take a tiny piece of tissue from a fish and put it in a special container with all the nutrients and things it needs to grow. They keep it warm and cozy, and the cells start to multiply and make more cells until they form a little piece of fish meat.
It's not exactly the same as catching a fish from the ocean, but it's a way to still enjoy the taste of fish without hurting the environment. Plus, since it's made in a lab, they can control what goes into it and make it better for our bodies too. It's pretty amazing, don't you think?
