My granddaughter was over today. I got out this big bottle of bubbles and we went outside where the wind was blowing. She took a bright purple wand, dipped it in the bottle pulled it out and waved it in the air and a dozen or so bubbles, perfect little spheres of soap took off carried by the wind. Some slightly larger than others, some bursting on the ground right after they were created but a few glistening in the sun took off skyward. A few were caught by an unseen stream of wind and pulled skyward ever higher and higher until they were out of sight. One floated by, a double bubble. One bubble failing to separate from another. Unable to gain height and headed toward the ground drawn by gravity....... Where it vanished......... suddenly...finally. It's not hard to imagine living in a double bubble.
