When I was a kid, I used to get chronic ear infections. At some point, they did some testing that involved forcefully streaming cold water into my ear. As you stated, it made my head spin something serious. As an adult I got a cholesteatoma in that same ear, which is probably directly related to the issue that caused so many infections in my younger days. I had surgery to remove it, and now I have to visit the surgeon once a year for ear cleaning because that ear doesn't self-clean so efficiently anymore. I have to use oil drops the night before so it isn't painful. I really dislike getting it done, but it sure feels better afterward. I've tried those effervescing concoctions, and I'm not convinced they actually do very much at all. It does sound really cool though.
