Leaving a bottle of water in your car on a hot, sunny day could start your car on fire.
Luckily, Dioni Amuchastegui, a battery technician with the Idaho Power Company, was sitting in his car when the sun reflecting through a bottle of water began burning his seat.
He shot the video below of it. You can see the smoke and burn marks.
Even the fire department confirms the possibility.
