I have also torn the magnetic film out of a 5.25" floppy to view a solar eclipse through. You just never know what they'll come in handy for.
OTOH I had hundreds of floppies and how often does a solar eclipse roll past L.A.? .... not often. I finally parted with all the old floppies, though I think I kept the WFW 3.11 3.5" diskettes, just for old time sake. And DOS is probably in that box too. The next time I come across it, it will get junked.
