Alright it has begun to rain here in California. Nothing crazy- but it's finally feeling a little like Fall. To explain to Hailey how the rain for lack of better term works I showed her this pin. We took a clear cup of water and filled the top with white shaving cream.
Then I took blue food coloring and began to drop the food coloring onto the clouds. I explained how the clouds fill up with moisture in the air and eventually the cloud becomes so full that it has to rain
(and then the food coloring began falling out!).
