why are bubbles round ?

Although this is not always the case you may have noticed this yourself, in some cases, however, the bubbles in a circular shape, although most of the times were not as well as they are trying to take a circular shape as much as possible. The reason lies in the phenomenon of "cohesion - cohesion" as these bubbles are only very thin layers of liquid material that originated them and their fractions, which together hold together because of attractive forces between them.

This arises from what is known as surface tension, which works to resist anything is trying to transit through it. Inside the bubble of air trapped there who is trying to get out, causing a strain on those layers of liquid "bubble wall" at home and abroad there are a greater quantity of air is also pressing on the other side of the surface of the bubble.

Now for the bubble the best way to resist those forces is to take the form most dense and compact, a circular shape, "remember not being able to break the eggs in case of pressing them vertically because of the principle of distribution of powers." At the present time scientists were able to work bubbles cubic and triangular several ways to study different surfaces from the perspective of engineering.

Now you can also respond to these questions .. why water droplets appear circular in shape, and why air bubbles appear in the water also circular in shape?
