Engineering360: "Physicist 'spins' mask filters in cotton candy machine"

This report says "standard plastics" which is misleading as there are big differences among plastics, as there are with foods or metals. The public misundertands plastics enough as it is, and such collective use of the term plastics further supports the falsely negative images that now exist. In fact, the author doesn't use water bottles (PET) or shopping bags (PE) as noted here, but rather PP and PS, which both melt around 100 C but don't become spinnable until much hotter, unless solvent-spun (lower temperature but need unpleasant solvents and provision for their recovery). In other words, the candy machine is another device that could be used to make mask material, but not a home DIY project.
