There are several videos out there showing a bottle of water, with the rays of the sun shining through it, starting a fire. So, the question is, can a bottle of water left in your car ignite a fire?
Well, if the situation is perfect, it is feasible for this to happen. But the chances of that happening are remote at best. So, what is a person to do? We recommend, for the environment, to use a metal water bottle. But sometimes, you don’t have it with you. If not, then just try to remember to take your bottled water out of the car with you or simply cover it up.
