Just blowing up the soap bubbles, we have fun in doing it but do you know why they round,
Let's know how,
The bubbles we make are not always spherical in shape, but they have the tendency to become perfect spherical in shape.
It happens because of the surface tension as all liquids have surface tension, which pulls the water molecules in the tightest possible groups and the tightest possible group of the collection of particles is in which then can transform is sphere.

Besides all shapes, the sphere has the smallest amount of outside region.
In short, bubbles maintain their spherical shape because that is the smallest shape to hold the volume of air and soap inside the ring of water.
Do you know that balloons, even planets and moons follow this and partially succeed in this.
