It's pretty obvious that plastic degrades over time and once it's extremely yellowed is likely to start breaking apart.
Unfortunately my friend yellowing bubbles is due to science, I tried to break down a very complex subject for a lay audience - I am sorry if I failed in that endeavour. As for conclusive evidence - there is no 100% conclusive evidence in anything in science, only best hypothesis and good predictive models. If you have questions about what was covered in the interview please PM me and I will try to explain it. But really my only intention was to help the collecting community.
