at 7:43 with how to stay safe in a thunderstorm. Turns out you don't have to be outside to be at risk. ABC's gio Benitez is here to explain. Good morning. This is really incredible. Listen to this. About 20 million bowls of lightning hit the ground every year. We've heard time and again that your car could protect you from that lightning. And that's partially true but wait until you see this video. Flash after terrifying flash, lightning strikes killing nearly 50 people across the country every year. I can't breathe. I can't get out of my car. Reporter: This central Florida woman driving down the road when a bolt of lightning struck her car. I was doing 45 and all of a sudden my airbags just went off. Bright white blinding light. The whole car just kind of lit up. Reporter: Windows blown out. Air bag deployed. Sheena easterly was lucky to walk away, her car, a total loss. I was holding on to the fridge with my right arm like this. Reporter: Macy Martinez was inside her home opening the refrigerator door when she was hit. Her mom shocked. I hear an explosion and my daughter is screaming. Reporter: This bruise on Macy's back where the electricity appears to have exited her Boyd. The most painful thing I've ever experienced. Reporter: And watch this lightning strike caught on dash cam in biloxi, Mississippi. The police officer saying the blast so bright it nearly blinded him. Lightning expert Dr. Joseph dyyer says the safest place to be during a storm. Get inside. If you can't get inside like a house or building, a car will do. Reporter: But he says if you're in the car, pull over on the side of the road. Don't touch things. If I can keep from touching the radio or plugging in my cell phone or fiddling with the window. Reporter: When you're indoors -- Don't answer the phone if there's a landline. Don't fiddle with the lamp. Don't connect yourself electrically to the outside world. Reporter: If you find yourself stuckout side with no cover -- A lightning safety position. Put your feet together and you squat down and make yourself into a little ball, minimal contact with the ground. Don't be a lightning rod. And here's another good tip you probably don't know. When you're inside your house during a storm don't shower or do the dishes. It turns out the electricity from a lightning strike can travel right through the plumbing. I've heard of that. My mom always said you can't get in the shower. Can't get in the bath. Another great excuse not to do the dishes. I was just going to say. You know, most people who get struck outside are men because we're too dumb to get inside when the storm is coming so get inside. That's a scientific fact. From meteorologist rob
