Blowing bubbles?????????

Question

this might sound stupid but when blowing bubbles why do they come out round even when you use a rectangle stick if you know what i mean

Answer 1

I was thinking this myself this morning!

Answer 2

Air pressure, it equal all over the inside of the bubble.

Answer 3

Bubbles are not spherical when in contact with otherbubbles SO surface tension.

Answer 4

Surface tension in the soap film will cause it to contract as far as it can. The fixed volume of air in the bubble will limit the degree of shrinkage, hence the shape formed is a sphere which has the maximum volume for the minimum surface area. If the bubble is big enough the weight of the film and of the air will cause the bubble to be flattened.
