A soap bubble Girl blowing bubbles Many bubbles make foam. A soap bubble (commonly referred to as simply a bubble) is an extremely thin film of soap or detergent and water enclosing air that forms a hollow sphere with an iridescent surface. Soap bubbles usually last for only a few seconds before bursting, either on their own or on contact with ...
Bubbles are like a "water and soap sandwich," with soap encasing a layer of water. In warmer weather, the air inside the bubble expands as it warms, popping the bubble before it gets far.
In a normal soap bubble, surfactants reduce the surface tension of the water and allow the bubble to form. To create a colored bubble, dye molecules must bond to the surfactants. Each dye molecule in Zubbles is a structure known as a lactone ring. When the ring is closed, the molecule absorbs all visible light except for the color of the bubble.
A foaming agent is a material such as a surfactant or a blowing agent that facilitates the formation of foam.A surfactant, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles.

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.

The term "bubble ring" is also used in other contexts. A common children's toy for blowing soap bubbles is called a bubble ring, and replaces the bubble pipe toy that was traditionally used for many years because the bubble pipe can be perceived as too reminiscent of smoking and therefore a bad example for children. Soapsuds are suspended on a ...
Bubbles in a foam of soap. Soap films meet in threes at about 120° along Plateau borders and these borders meet at vertices at about the tetrahedral angle. Plateau's laws describe the structure of soap films. These laws were formulated in the 19th century by the Belgian physicist Joseph Plateau from his experimental observations.
