I am currently reading an article on the Internet which has the phrase: "Teflon just flakes in a solution". It is in fact part of the following longer sentence, which I think would help to explain its meaning:
"Post-it Notes were once a scientific curiosity, Teflon just flakes in a solution and penicillin contamination in a petri dish."
Now overall what I understand is that this sentence talks about the circumstances of three scientific discoveries. The first (post-it notes) and the third (penicillin) are not hard to understand. The second, however, is what I dont get.
I have been trying to search on the web for meanings of the word "flake", but none have the form "flake in". So I guess I have two questions:
1/ What does "flake in" mean?
2/ What does "Teflon flakes in a solution" mean in the above sentence?
Thank you very much for your help.
