Surface tension. That is all a bubble is; water and soap strengthening each other's weak points. Spheres with swirling iridescent colors, like oil slicks, but purer, less distasteful.
One would be thought mad to stand and stare at a puddle of oil. But bubbles are made to be watched with breath-holding anticipation for the inevitable pop bursting open nostalgia in our hearts. There is happiness and sadness in equal measure when studying a bubble.
We will watch and wonder and let our mouths hang open. We will smile and clap and laugh out loud. We will cheer the bubble that makes it to the sky, hoping we too could hold the clouds inside ourselves to delight, to awe, to inspire. And we will sigh, looking down at our bare toes in the grass, wishing the magic was more than simple science floating on air.
