AI Thread Summary
The discussion centers on the potential for fingernails to create microplastics when they come into contact with plastic surfaces, such as the edge of a bottle. One participant expresses concern about whether this interaction could lead to the formation of microplastics, despite no visible damage being observed. Another participant challenges this notion, suggesting that the question lacks scientific basis and requests clarification or references to support the claim. The conversation also touches on the possibility of scratching plastic off food containers or utensils, confirming that this can indeed lead to ingestion of microplastics.

For example, I have some fingernails, I touch the mouth of a plastic bottle but the fingernail hits on the edge, I could feel it is a big hit, of course no observable damage is seen because it is just a fingernail, could this already create some microplastics that we don't see?

You have asked questions on microplastics before and gotten answers. This seems like speculation, not science.

I do not understand what you are asking - please give us a reference. Thanks

If you are asking if you can scratch plastic off of food containers/utensils and ingest it, the answer is of course yes.

You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
