Did you notice the power lines? Those carry electricity! People cut off tree branches near power lines so trees don’t get zapped like this! Electricity can make sparks, which can start fires.

There’s always electricity flowing inside of the power lines. They’re
like tubes with electricity inside. Sometimes during storms, if the
cables break, you can see the electricity starting dangerous fires.

Electricity makes cool branching patterns when it hits things. Could you invent something for lightning to hit? Hint: Electricity likes to hit metal. (It’d be dangerous to really do this, but you can pretend!)

A band called “ArcAttack” sometimes wears metal suits. Imagine
playing a guitar while being struck by lightning! (It doesn’t hurt them,
but only because the suits are special, built to be safe!)
