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 ...
Iridescence in soap bubbles. Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films.
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.
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.
Emulsion: miniemulsion, microemulsion, milk, mayonnaise, hand cream, hydrated soap: unstable emulsion of a soap bubble (at ambient temperature, with iridescent effect on light caused by evaporation of water; the suspension of liquids is still maintained by surfacic tension with the gas inside and outside the bubble and surfactants effects ...
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ...
"Talk of bubbles in tech or AI, or in investment strategies focused on growth and momentum, obscures the mother of all bubbles in US markets," he wrote. "Thoroughly dominating the mind space of ...
A soap bubble is a very thin film of soap water that forms a hollow shape with an iridescent surface. Soap bubbles usually last for only a few moments and burst either on their own or on contact with another object. Due to their fragile nature they have also become a metaphor for something that is attractive, yet insubstantial.
