Lightning Rod


Sometimes when people want to protect buildings from getting hit by lightning, they will put a tall metal pole on the top of their building, connected to metal all the way down to the ground.

Lightning electricity goes after the tallest and most conductive thing to strike, so it will hit the lightning rod and go straight through to the ground and not hurt the building.
