Everyday, we wash our hands. Not once, not twice but many times of the day. And we often use soap.
I wanted to see what does that soap look like up close. I took some of the frothy soap and put it on a glass slide. Here is a sneak peak.
What you see are soap bubbles; arranged in numerous geometries. What looks static at first, starts morphing and changing very soon as the soap bubbles try to minimize the net surface energy by changing morphologies.
See if you can decipher the rules for what geometries are stable – and which ones are unstable?
