What is static electricity?
For grown-ups: the science
Static electricity happens when invisible, tiny electricity builds up, such as when things rub together.
Static electricity happens when electrons move as materials touch or rub, creating an uneven amount of electricity. Charged things can pull together or push apart with electric force. When electricity suddenly moves through the air, it makes a spark or a snapping sound. On dry days, electricity does not escape as easily, so static electricity is easier to notice.

When you pull off a sweater and hear a snap, why does that happen?
When things rub, tiny bits of electricity move to one side. Invisible electricity can build up on your clothes and body.
Built-up electricity pulls different electricity toward it. Then your hairs move apart and stand up all fluffy.
When lots of electricity builds up, it can jump across the air. That makes a tiny flash and a snapping sound.
Static electricity is tiny electricity that builds up on things.
