A leak is like when you have a cup full of juice and there’s a tiny hole in it. The juice slowly drips out, and you might not notice it at first. But soon, your cup is empty, and there’s a sticky mess on the table. This is because the juice found a way to escape through the hole.
Imagine your favorite balloon. When you blow it up, it holds air inside. If there’s a small hole, the air sneaks out, and the balloon gets smaller and smaller until it’s all flat. The air is escaping through the hole, just like the juice from the cup.
Think of a secret you’re trying to keep. If you tell just one friend, and they tell another, soon everyone knows! The secret has leaked out, just like the juice and the air. A leak lets something get out when it’s not supposed to. It can happen with juice, air, or even secrets. Keeping things sealed tight helps prevent leaks, whether it’s a cup, a balloon, or a secret.
