Bubble (physics)

Air bubbles rising from a scuba diver in water
A soap bubble floating in the air

A bubble is a globule of a gas substance in a liquid. In the opposite case, a globule of a liquid in a gas, is called a drop.[1] Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance.
