During a thunderstorm, avoid open spaces, trees, telephone booths, and ballparks. The safest place to be is in a building, preferably one with a lightning rod. The rod offers protection by intercepting lightning—an electrical charge—and transmitting its current into the ground. The other safe place is a car with the windows rolled up, as long as you don’t touch any of the metal parts. If lightning strikes, the car’s metal body will conduct the charge down to the ground—contrary to popular belief, the rubber of the wheels offers no protection.
