Firefighters are warning that plastic water bottles left in cars can start fires. Sunlight shining through the bottle can focus heat onto flammable materials, like car seats, acting like a magnifying glass.
One firefighter in Idaho found his seat smoldering after a bottle sparked a fire. To stay safe, keep bottles out of direct sunlight—store them in the glove box or use opaque bottles.
A small change can prevent a serious fire. Stay aware this summer.
