A great video shows two bubble rings that meet under water.
The pair is made by a diver from the camera who then records them while gently floating to the surface.
When they finally meet, the bubbles touch each other and together form a single larger bubble ring.
The ring reflects a few seconds before it falls apart into the water.
A bubble ring is an underwater vortex that arises when a bag of air occupies the center of the swirl.
They are actually made from two different rings, one in the other, turning in the same direction.
The outer ring is made of water and the inside is made of air.
The ring and the nearby water spinning as it travels through the water and pushes it in a certain direction.
This is compared to the way a bracelet rotates when this person's arm rolls down.

In the video, the rings combine the moment they touch – a common phenomenon in bubbles.
Bubbles always try to minimize their surface so that two bubbles come together to share a common wall.
Bubble rings are often made playful by dolphins using air from their bladders.
According to Leandro Stanzani, president of the Oltremare water park in Italy, the creatures blow up the bubbles to have fun.
He said: "Dolphins are very complex and social animals, they like to play alone, with other dolphins or even with what appears between their fins.
& # 39; If they do not have toys, they make them themselves. Air bubbles and air rings are homemade toys.
& # 39; They create the shapes by blowing air quickly under the surface of the water.
Sometimes they form rings using the vortex created by their rapid swim by injecting air into them. & # 39;
