Surface Tension creates spherical bubbles | Liquids | Physics

Описание: The video demonstrates that soap bubbles are spherical regardless of the shape of the loop that created them. There is an informal introduction to the mathematical concepts of surface area and volume and how the same force (surface tension) is responsible for always producing the spherical shape. It does so in an attempt to achieve the smallest volume of bubble, because it is like an elastic force equally pulling inward in all directions. The only shape that can result from symmetrically acting forces is a shape that is symmetrical in all directions - i.e. a sphere.
