Water Bottles Left in Cars Can Start Fires [Watch]
My little brother would use a magnifying glass to melt his toys in the summer. The sun would come through the glass and burn the plastic. This is no different than sun through a water bottle in your car.
I hate to sound ignorant but it never occurred to me that something like this could happen. With our temps being in the mid to upper 90's and that long stretch of over 100 degrees (more is coming), of course this could happen to us.
Having a bottle of water in your car reflecting the sun onto your seat or hard plastic center console could really heat things up. A man was sitting in his truck eating lunch when he noticed smoke out of the corner of his eye. It was the sun burning through a bottle of water onto his seat.
If nothing else, this summer heat wave is helping us keep our cars clean.
