Well, I spent nearly an hour searching for my stash of old filter gaskets. I see them every so often and probably moved them the last time because they were on the pegboard, but are not now. I did manage to get two gaskets from filters on the work bench that I didn't get around to cutting open yet. They string together nicely though it throws a curve in at the knot. It's okay though as that will just help in the bungieeness of the whole string. Someday, I'll find them. Have to figure what to do with different sizes, most of mine are from FL1A, but a couple smaller FL400s.
Now it might be fun to test the strength. Anyone with an old fashioned weight set? Hang weights from one gasket and see how much it takes to break the gasket. I am guessing the gaskets will easily sustain 200+ pounds. We might even be able to connect rear bumpers and do a truck pull with these things hooked up in tandem.
Now another idea is could the gasket be used as a teething ring? Wife will be watching a neighbor's baby next thursday. Would be worth a try. What the parents don't know won't hurt them. I doubt the kid would choke as the ring is too big. Only question is whether these gaskets have any lead in them. I am not worried about the oil as I washed them really well.
