The ocean is full of mysteries and wonders, but one of the most fascinating and playful underwater phenomena is the bubble ring. These mesmerizing rings of air, created by dolphins, whales, and even scuba divers, spin like underwater tornadoes and can remain stable for several seconds before dissipating. Bubble rings are not just a scientific curiosity—they are a testament to the intelligence, agility, and playful nature of marine life.
In this article, we will explore:
-
What are bubble rings and how are they formed?
-
The role of bubble rings in marine life, particularly among dolphins and whales
-
How scuba divers create bubble rings underwater
-
The science behind their stability and motion

Fun facts and the cultural significance of bubble rings
If you love the ocean and the intriguing behaviors of marine animals, dive in and discover the magic of bubble rings!
What Are Bubble Rings and How Are They Formed?
A bubble ring, also called a vortex ring, is a circular, self-contained bubble that maintains its shape as it moves through water. Unlike regular air bubbles that rise quickly and burst, a bubble ring spins on itself, creating a vortex that helps it remain stable for longer.
How Bubble Rings Form？
Bubble rings are created when air is expelled into the water and given a spinning motion. This can happen in various ways:
✔ Dolphins and whales release air from their blowholes and control the shape and movement of the bubbles with their noses or fins.
✔ Scuba divers can form bubble rings by exhaling air in a specific way while tilting their heads back.
✔ Man-made experiments in water tanks have shown that bubble rings can be artificially generated using special underwater devices.
Bubble rings are a perfect example of fluid dynamics at work—the vortex structure keeps the bubble ring from breaking apart immediately, allowing it to drift and spin gracefully through the water.
Role of Bubble Rings in Marine Life！
A. Dolphins: Masters of Bubble Ring Play
Among all marine creatures, dolphins are the most well-known for their bubble ring tricks. These highly intelligent mammals have been observed creating, manipulating, and playing with bubble rings in the wild and in captivity.
✔ Dolphins use their blowholes to create bubble rings, often spinning them with their fins or noses.
✔ They can make large and small rings, sometimes biting at them to break them apart or pushing them forward like a game.
✔ Some researchers believe that dolphins use bubble rings not just for play but also as a form of communication with each other.
Why do dolphins create bubble rings?
-
For entertainment—dolphins are naturally playful creatures.
-
As a display of intelligence and problem-solving skills.
-
To interact with other dolphins in their social groups.
B. Whales and Bubble Rings
Though less commonly observed, some species of whales, particularly beluga whales, have also been seen creating bubble rings. Their technique is slightly different from that of dolphins, but the result is just as mesmerizing.
✔ Beluga whales in aquariums have been recorded blowing bubble rings for fun, much like dolphins.
✔ Larger whales, like humpbacks, create bubble structures (though not perfect rings) as part of their hunting strategy called bubble net feeding.
These observations suggest that bubble manipulation is not just limited to play but may also have practical uses in the marine world.
How Scuba Divers Create Bubble Rings？
Bubble rings are not only the domain of marine mammals—skilled scuba divers can also create these captivating rings as an underwater trick. It requires practice, controlled breathing, and an understanding of water dynamics.
Steps to Create a Bubble Ring as a Scuba Diver？
-
Descend to an appropriate depth (at least 6–10 feet underwater).
-
Maintain a stable position, ideally floating on your back or upright.
-
Take a deep breath and close your lips into an "O" shape.
-
Exhale a short, controlled burst of air, tilting your head slightly back.
-
Keep the motion smooth—the air should release in a tight, circular shape to form the ring.
-
Observe the bubble ring drift upward and maintain its shape before eventually breaking apart.
✔ Advanced divers can create multiple rings, push them forward, or even merge two rings into one.
✔ Some divers perform bubble ring tricks for underwater photography and entertainment.
This playful yet challenging skill adds an extra layer of enjoyment to scuba diving adventures, allowing divers to interact with the water in a unique way.
The Science Behind Bubble Ring Stability and Motion？
Bubble rings may look like simple underwater fun, but they are actually a fascinating example of fluid dynamics. Their stability and motion are dictated by vortex physics, which keeps them from immediately collapsing.
How Do Bubble Rings Stay Intact?
-
When air is expelled into water, it naturally rises toward the surface due to buoyancy.
-
If the air is given a spinning motion, it forms a vortex—a self-contained ring of air that moves through the water without dispersing immediately.
-
This vortex motion creates a pressure difference, allowing the bubble ring to stay in shape as it rises slowly.
Why Do Bubble Rings Eventually Disappear?
-
As the bubble ring rises, water pressure decreases, causing the bubble to expand and eventually break apart.
-
External disturbances, such as water currents or interactions with other objects, can cause the ring to collapse.
This scientific explanation helps us appreciate just how precise and skillful marine animals and divers must be to create perfect bubble rings!
Fun Facts and Cultural Significance of Bubble Rings！
