Bubbles In The Rain

A quick everyday-science aside: The other day, I was hanging out with my 22-month old niece, watching her blow soap bubbles. A light rain was falling and had moistened all the plant leaves so that the bubbles could come to rest on the leaves without popping. Soon the nearby plants had grown a crop of irridescent fruit. As the rain fell on the bubbles they diluted the soap solution but managed not to destroy or burst the bubbles. In fact, the soapy, irridescent part of the solution sank to the underside of the bubble leaving the top of the sphere mainly a water bubble. The nifty part is that the watery top of the bubble was almost invisible, while the soapy bottom looked the same as usual. Overall it gave the appearance of a colorful glass sphere with the top broken off, and as more rain fell, more of the bubble seemed to disintegrate from the top downward, right before our eyes.

Isn't science cool?
