Not sure if this is an interesting physics question, or just a
curiosity, but has anyone seen the new Sun Chips biodegradable chips
bag? It is LOUD! Compared to any other plastic-type bag, it is
astonishingly loud, and I was wondering which properties of a bag
affect the loudness. Since it is biodegradable, it isn't made of the
same stuff, but if feels mostly the same (perhaps a bit stiffer).
Anyway, I thought there might be some interesting physics activity in
there somewhere, but I am not sure what. If not, at least it is
curious. (you can google loud sun chips bag and get a lot of hits,
including a description of the bag itself).
