Everything vibrates, even things that seem still, like your favorite toy or the floor you walk on.
Imagine you're pushing a swing. You give it a little push, and it goes back and forth, that's vibration! Now imagine you’re not pushing it anymore, but it’s still moving slowly, going back and forth, just like when you're dozing off and your toy car moves slightly on the floor.
How Things Vibrate
Every object has a kind of “inside rhythm.” A drum vibrates when you hit it, and your voice vibrates the air so you can be heard. Even things that seem solid, like your bed or the table, are made up of tiny parts called atoms, which are always moving and bumping into each other.
Sometimes these vibrations are big enough to feel, like when you press a button on a phone, and it makes a click. Sometimes they're so small, you can’t see them, but they’re still there. Like how your favorite cookie stays soft because the tiny parts inside it are always moving!
So, everything is vibrating, even if you don’t notice it at first! Everything vibrates, even things that seem still, like your favorite toy or the floor you walk on.
