A whole pack of Oreo cookies was finished, the clear plastic wrapper was sitting on a open notebook. I observed the most curious phenomenon. Between the plastic wrapper and the notebook was a black cookie flake about two mm in length and quite flat.The black cookie flake was, I'm guessing, statically attracted to the under side of the plastic. It hung vertically touching at a point. After a short while it dropped a distance of about 3 mm momentarily touched the notebook paper and then "jumped" back up and was again statically attracted to the plastic. Another 5 seconds would elapse and the process would repeat it self, drop, jump, wait, drop. Sitting back amused I became dejected at the thought the Feynman would have quickly figured out what was happening while I was blank. Any Feynman out there care to explain the physics to me? Thank you for any thoughts.
