A bubble ring, or toroidal bubble, is an underwater vortex ring where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins poloidally as it travels through the water, much like a flexible bracelet might spin when it is rolled on to a person's arm.
Underwater explosions are categorized by the depth of the explosion. Shallow underwater explosions are those where a crater formed at the water's surface is large in comparison with the depth of the explosion. Deep underwater explosions are those where the crater is small in comparison with the depth of the explosion, [2] or nonexistent.
If the bubble is not long enough to encompass the object, especially at slower speeds, the bubble can be enlarged and extended by injecting high-pressure gas near the object's nose. [1] The very high speed required for supercavitation can be temporarily reached by underwater-fired projectiles and projectiles entering water.
Cavitation (bubble formation/collapse in a fluid) involves an implosion process. When a cavitation bubble forms in a liquid (for example, by a high-speed water propeller ), this bubble is typically rapidly collapsed—imploded—by the surrounding liquid.
Fine bubble aeration is an efficient technique of aeration in terms of oxygen transfer due to the large collective surface area of its bubbles. Fine bubble aeration is an efficient way to transfer oxygen to a water body. [8] A compressor on shore pumps air through a hose, which is connected to an underwater aeration unit.

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.
