Показать описание
Have you ever wondered why air bubbles float to the surface of water? Or why soap bubbles are so spherical? The answer to both of these questions has to do with excess pressure.
Excess pressure is the difference in pressure between the inside and outside of a curved surface. It is caused by surface tension, which is the tendency of a liquid surface to shrink to the smallest possible area.
