In 2017, a video from Idaho Power went viral after a video warning created by one of their Stations Battery Techs went viral. As the tech tells the story, he took an early lunch break in his vehicle and noticed smoke rising from the passenger seat of his car.

Sunlight beamed through the driver’s side window and focused to a single point as it refracted through the bottle.

If you ever used a magnifying glass to burn ants on your driveway or newspaper in science class when you were younger, it’s the same action.

A few years after the Idaho Power video took off, a Central New York Firefighter did a news story with WSTM-TV where he demonstrated how water bottles could start a fire in your vehicle.
