Spiega i fulmini

Spiega i fulmini? Bah! It’s not like you need to know this stuff. Basically it means “explain lightning.” Lightning is just a big spark of electricity that happens in the atmosphere. It’s created when the negative and positive charges in the air separate and then come back together. The spark is like a big sparkler! Fun fact: you can hear thunder from up to 10 miles away, but you can only see the lightning if it’s within about 3 miles of you.
