This is a must see video for anyone who has wondered why many plastics turn yellow with time. It covers why the yellowing occurs, it busts many myths about the causes of plastic yellowing. It has information about numerous experiments Jeff did with various products, chemicals and procedures. You do not need a degree in Chemistry to understand the video, though, to be honest, if you had a General Science class in your freshman year of High School as I did, that had two six-week periods of physics, two six-week periods of chemistry, and two six-week periods of biology you should be able to follow the chemistry.
And if you don't need the information now, you will in the future. Here is the link from Jeff's message to the video: https://youtu.be/YPl356YKcVs Bradley Kuss GRANBURY TX
