WARNING: Water Bottles In Hot Cars Can Lead to a Fire
Did you know leaving a water bottle in the car during summer months is extremely dangerous?
A water bottle left inside a car on a sunny day could ignite the upholstery and start a fire. Seriously, it can, and has. It's almost like the magnifying glass effect on your car, and papers inside. It could cause a massive fire.
Given the right kind of plastic container and the right environmental conditions, sun shining through a water bottle can indeed lead to combustion. A round plastic bottle filled with clear water can act as a lens that concentrates the sun's energy on one point."
Hoax Slayer points out if the sun's energy is concentrated through a water bottle on to combustible material, then it is possible that fire could result.
As a precaution, it is advisable to remove plastic water bottles from cars left in the sun or cover them so that they cannot act as lenses. Keep that in mind this summer.
