What is bubble ring?

A bubble ring is a toroidal vortex that forms underwater when air is exhaled in a controlled manner. They are typically created by scuba divers or aquatic mammals such as dolphins and whales. The exhaling of air in a specific way causes the air to form a circular shape, which then rotates and maintains its shape as it moves through the water.

Bubble rings are often used for entertainment or as a form of communication among marine animals. They can be quite mesmerizing to watch as they slowly drift and spin through the water. Some divers even practice creating and perfecting bubble rings as a form of underwater art or a fun way to pass the time during dives.

Creating bubble rings requires a bit of practice and skill, as the diver needs to exhale just the right amount of air in a controlled manner to form a stable ring. With practice, divers can create larger, more intricate bubble rings that can be quite impressive to witness.
