Figured I'd post my simple fix for a loud stir bar. I have a DIY stir plate and a flat bottomed glass jar for my starters. The rattling drives me nuts. I had some leftover rubber rings from Lowes that fit right over the bar. Two in the center and two on opposite ends. Now it runs silent. Someone probably came up with a fix like this before, but either way if you have a noise issue try it out.
O-rings can be found in Lowes in the plumbing section near the sink/drain isle. The old packaging has since been lost but they appear to be 1cm ID. I would take the stir bar in with you and try some out. I believe the rings only cost 1-2$ for around ten.
Hope this simple fix is useful to some of you. It also seems to stop the plate from throwing the bar.
