Big Bubble

A giant bubble wand in the park. Air moving through the wand's rope loop grows the film: move too slowly and nothing happens, too fast and it tears, and the bigger the bubble gets the less it can take. The wind does half the work and keeps changing, and you can only read it from the flags, the kites and the leaves. Lift your finger to close the bubble and send it floating off over the park. Every dip spends soap. Later the gusts come, kids start chasing the small bubbles, and the breeze swings around.
