Be careful with your water bottles, said one battery technician at the Idaho Power Company.

Dioni Amuchastegui shared the scary reason why you should never leave water bottles floating around in your car on a hot day in an experiment posted to Facebook.

In a video, the technician said he learned about a car fire hazard from experience when one day while taking a lunch break, he looked over and saw smoke coming from the seat of his truck.

Apparently, the sunlight magnified through a bottle of water reached a high temperature and started a small fire. Amuchastegui said:

“I looked over and noticed light was being refracted through a water bottle and starting to catch the seat on fire.”

After the clip caught the attention of millions, fire officials warned that leaving water bottles in your car has the potential to spark a flame although the risk of someone’s car going up in flames is low.

David Richardson with the Midwest Fire Department in Oklahoma explained to KFOR:

“The sunlight will come through, when it’s filled with liquid, and act as a magnifying glass as you would with regular optics.

It uses the liquid and the clear material to develop a focused beam and sure enough, it can actually cause a fire, a combustion.”

The extra heat in Amuchastegui’s incident burned his truck’s interior and can be pretty dangerous.

After the near disaster Melissa Thom, a corporate communications specialist for Idaho Power, told CBS News:

“Everybody was shocked.”

She added:

“A lot of people on his team thought he was making it up.”

Richardson told the outlet that vinyl will start to burn at 455 degrees. However, drivers only need to worry about leaving clear water bottles in sunlight.

Leaving out dark-colored drinks or tinted bottles is perfectly safe.
