This was an experimental day. I had the sprinkler going (and locked in position) and the sun was just right in the sky to cause the rainbow effect. I was hoping to do a rainbow over a rainbow, but it never quite worked. The extra moisture in the air didn't hurt though. I did notice sometimes the bubbles would pass right through the mist, and other times the bubbles would pop when hit by a jet of water. I've since practiced bubbling outdoors in slight rain and heavy rain and have found the same to be true~little soft drops pass through the bubbles. Big rain drops cause the bubs to burst.
