    I know, I tried it. What's very frustrating is how any small movement makes
    the bubble go away. But then, I didn't seem to have much success with a pan
    of water in my garden either. Maybe oil would be better? Anyway, the bubble
    horizon is on order, and I'll see what my first sights will be. Not good I
    imagine...
