It’s horrible. You hop around frantically, in a sort of sideways head-banging session, but that rusty sound never escapes! I hate it when I have water in my ears! The only solution I’ve found is to add more water. Because I think what happens is you have a little tiny drop in there somewhere, hanging out with your ear drum. So if you add more, the molecules will join hands and happily exit the ear with one swift head flick. Try it.
