why do bubbles in soft drink are spherical?

Answer 1

all bubbles are spherical.this is due to surface tension of water.the surface of the water behaves like a stretched piece of elastic.hence it tries to reduce its surface area.since among all the shapes the surface area of the sphere is least it forms a sphere .

Answer 2

Because a spherical bubble has the least energy in the surface tension of its skin. Therefore spherical is the stable state for a bubble. They can wobble but they will always settle to a sphere once the wobbling stops.

Answer 3

In olden times, the soldiers in a castle would drop a measured amount of molten iron over the side of the castle into the moat - later, they would go into the moat and collect the cannon balls. The molten metal would form a shape which would represent the effects of no uneven pressures being exerted on it - a sphere.
This same principal is seen in soap bubbles and soda bottles. The shape which requires no uneven internal or external pressures is a sphere.

Answer 4

because the gas inside a liquid exerts an equal pressure all around thus naturally forms a spherical bubble.
To make a shape with corners has problems as opposite corners are longer distances compared to opposite sides thus they would require different pressures inside the bubble to form the shape and would require different phyics to the natural world.

Answer 5

because of the acid and other chemical reaction that occurs in the beverage
