Inside the Bubble
The bubble, made of dish soap and water, exists because it has surface
tension. The soap decreases the water’s surface tension and helps to
stabilize the bubble, known as the Marangoni effect. The Maragoni
effect, by definition, is the mass transfer in a liquid layer due to
surface tension differences. The bubble’s is a sphere, as a sphere
has the smallest possible surface area for a given volume. In this
particular photo, the person on the grass was not intentionally inside
of the bubble and the photo was not meant to include the parking lot
in the background; it just happened that this one photo appeared to
completely encompass my roommate.
