surface tension
Beakman explains what adhesion and surface tension are while making DIY bubbles. Then using a rubber band, he shows that the soap film will stick to any edge inside of the rubber band regardless of shape. If you remove the rubber band, then the molecules will stick together in their smallest shape which is a sphere. Then a man demonstrates that there can be square "bubbles" and rainbow shaped "bubbles."
