it is simply due to property of surface tension acquired by liquids,according to which they tend to minimise their area and for a given volume sphere has minimum area.

We can jabber on about air pressure and so on but the sphere is a primary form that aggregation creates.
Whether there is pressure or not (as in a vacuum)
particles will naturally tend to coalesce until they form a spherical shape. Unless other forces intervene, masses tend to form a spheroid shape.
Bubbles are round like the Earth, like the sun, like the stars, like the planets, like the rain (minus gravity), etc.

Oh good grief I had this question in a science exam way back in.......well you don't need to know. we had just been learning about air pressure and doing the silly experiments like soothing a sheet of a large news paper over a wooden as they were in those days ruler that hung over the edge of a table and hitting it with the palm of hand to break it .... the paper being the thing holding the ruler tothe desk. Well the outcome being that air pressure is I believe and memery serves me right 15 lbs per square inch around the Earth's surface. THE ANSWER TO YOUR Question is because air pressure is equal i.e inside and outside of the bubble, underneath, ontop and from the sides therefore the shape would have to be subject to an unequal force from one aspect to make it anything other than round........I didn't think of that in the exam .......such a dimwit at times lol

To be able to use the least amount of surface, the liquids of a bubble create a round sphere like shape which uses the least amount of surface as compared to a square or rectangle.
I had a project lol thats how I know

Bubbles would tend to collapse, but it is the air inside that stops them from doing so, thus they adopt the shape with the least possible surface area. Spheroid

air pressure inside the bubble is same. So, the pressure on the surface of buble also same.

Maybe they're taught by the same instructors that teach people to cut corners when driving.

because any other shape would be a trip. i mean some on...square bubbles? are you serious?

to make a long story short - its surface tension.
