Here lol I googled it
The surface tension of a bubble is like the stretch of a balloon. This stretch attempts to shrink the bubble or balloon to a very small size. Think of an uninflated balloon.
When there is air trapped inside a bubble or balloon then it can't shrink too much because that will compress the air. So, the effect of the stretch if to make the bubble take a shape that has the smallest area (the amount of surface) for a given volume (the amount of air inside).
We can see what sort of shape have a large surface by looking at the surface, the perimeter, of a two dimensional shape:

Pascal's law.
The pressure will be equal at all points inside the bubble, which causes all points on the outside surface of the bubble to have the same amount of force pushing against it. This means all of the points will be an equal distance from the center of the bubble unless there is an outside force acting on the bubble (like gravity or wind). A sphere can be described as a 3 dimensional shape with all points on the surface an equal distance from it's center... "round".

Bubbles are round for one simple reason. Pressure. Think, the only shape where there is equal distance from the center to the edge is a circle. This is caused in bubbles because the pressure is going out in every direction at an equal force.

what a great question!
Bubbles are round because the round shape makes the best use of space. Equal pressure on the inside and out means it will be a circular shape.

Air pressure is equal; causing a set diameter between any two opposing points on the surface of a bubble.

"minimal surface structures." This means that they always hold the gas or liquid inside of them with the least possible surface area. The geometric form with the least surface area for any given volume is always a sphere, not a pyramid or a cube or any other form.

because it is a low energy state. ie the surface tension is equal in all directions and it is a minimum energy state. so the bubble will naturally move to that equilibrium.

i have bubbles ever where so when ever every one is stressed all they have to do is blow bubbles actually we even have to keep them on the bathroom so when one of the children needs go go do their thing they cant so it unless they blow the bubbles get the ones that have flavored smells they are great!

cuz ther is equal air pressure acting in all directions
