In many ways I liked the 5.25" floppies better than the 3.5" floppies.
A friend once accidentally knocked a glass of coca-cola over and it spilled all over his favorite C-64 game disk (sorry it's been too many years, I can't seem to remember which game). Anyway, he slit the 5.25" disk jacket open with a razor blade, pulled the media out and rinsed the media off under the faucet. He then took a new blank 5.25" disk and slit the jacket open on that and pulled the media out. Next he took the washed and dried media and inserted it in to the new jacket. A little cellophane tape to seal the jacket back up and he was gaming again.
(This is also a good example of why you should always have a back-up.)
