A friend has this clear plastic water container, which he takes in his car just in case he breaks down (along with blankets and stuff). What is strange is that the container is starting to turn green inside!
It is exposed to some heat, from inside the car, and often left on the parcel shelf. What is going on, why is the plastic turning green inside?
