: Does anyone know about "on the bubble?" I'm guessing that the image is of a spirit level. Any insight into when or how the phrase entered everyday speech as meaning something like "could go either way" or "up in the air"? There's a poker usage that seems a little different: http://poker.about.com/od/pokerglossary/g/bubble.htm
That would be my guess too. I thought we'd discussed this phrase here before. But I couldn't find it in the archives.
