What is a bubble?
A bubble is a thin film of liquid that encloses a gas or air. The film can be made of any liquid, such as water, soap, oil, or even blood. The gas or air can be any substance that can be dissolved or entrapped in the liquid, such as carbon dioxide, oxygen, nitrogen, or helium. A bubble can also be a globule of gas or air in a liquid or a solid, such as a bubble in a soft drink, a bubble in glass, or a bubble in ice.
How bubbles form and why they are spherical
Bubbles form when a gas or air is introduced into a liquid or when a liquid is agitated or heated. For example, when we blow air through a straw into a glass of water, we create bubbles. When we shake a bottle of soda, we release carbon dioxide bubbles. When we boil water, we produce water vapor bubbles.
Bubbles tend to be spherical because this is the shape that minimizes the surface area of the film for a given volume of gas or air. This means that the spherical shape requires the least amount of energy to maintain. If a bubble is distorted from its spherical shape by external forces, such as gravity or wind, it will try to restore its spherical shape by reducing its surface tension.
How bubbles interact and create patterns
When bubbles meet each other, they will merge their walls to minimize their surface area. If two bubbles of the same size meet, they will form a flat wall between them. If two bubbles of different sizes meet, the smaller bubble will bulge into the larger one. When three or more bubbles meet, they will form walls at an angle of 120 degrees to each other. If enough bubbles meet, they will form hexagonal cells that resemble honeycombs.
We can observe these patterns by making prints of bubbles or by blowing bubbles between two clear plates. We can also see these patterns in nature, such as in foam on the sea surface or in froth on beer.

What are the types of bubbles?
Bubbles can be classified into different types based on their medium (liquid or gas), their context (economic or physical), and their function (medical or technological). Here are some examples of different types of bubbles:
Bubbles in liquids and gases
Soap bubbles
Soap Soap bubbles are the most common and popular type of bubbles. They are made of a thin film of soap and water that reflects light and creates iridescent colors. Soap bubbles can be blown by using a wand, a pipe, or even our hands. Soap bubbles can also be filled with other gases, such as helium or hydrogen, to make them float or explode.
Water bubbles
Water bubbles are bubbles that are made of pure water without any soap or other additives. They are usually formed by boiling water or by spraying water into the air. Water bubbles are transparent and colorless, and they tend to pop quickly when they touch the air or any solid surface. Water bubbles can also be frozen to form ice bubbles, which have a crystalline structure and can last longer.
Air bubbles
Air bubbles are bubbles that are made of air trapped in a liquid or a solid. They are often formed by injecting air into a liquid, such as in a syringe or a pump, or by trapping air in a solid, such as in a sponge or a foam. Air bubbles can affect the properties and behavior of the liquid or the solid, such as its density, viscosity, buoyancy, and sound transmission.
Bubbles in economics and finance
Market bubbles
Market bubbles are situations where the price of an asset, such as a stock, a bond, or a commodity, rises far above its intrinsic value due to excessive speculation and demand. Market bubbles are often driven by irrational exuberance, herd behavior, and positive feedback loops. Market bubbles can burst suddenly when the supply exceeds the demand, when the expectations change, or when a shock occurs. Market bubbles can cause severe losses for investors and affect the stability of the economy.
Commodity bubbles
Commodity bubbles are a type of market bubble that involves the price of a raw material, such as oil, gold, or wheat, rising rapidly and unsustainably. Commodity bubbles are often caused by supply and demand imbalances, geopolitical events, natural disasters, or market manipulation. Commodity bubbles can have significant impacts on the production and consumption of goods and services, as well as on inflation and growth.
Credit bubbles
Credit bubbles are a type of market bubble that involves the expansion of credit and debt in an economy beyond its capacity to repay. Credit bubbles are often fueled by low interest rates, lax lending standards, financial innovation, and excessive leverage. Credit bubbles can create asset price inflation, overinvestment, malinvestment, and moral hazard. Credit bubbles can collapse when the borrowers default on their debts, when the creditors tighten their lending conditions, or when the interest rates rise.
Bubbles in physics and chemistry
Magnetic bubbles
Magnetic bubbles are regions of magnetic field that are isolated from the surrounding magnetic field by a thin layer of magnetic material. Magnetic bubbles can be created by applying an external magnetic field to a magnetic medium, such as a thin film or a nanowire. Magnetic bubbles can be manipulated by using electric currents, magnetic fields, or spin waves. Magnetic bubbles can be used for data storage, information processing, and spintronics.
Bubble fusion
Bubble fusion is a hypothetical process of nuclear fusion that occurs inside collapsing bubbles in a liquid. Bubble fusion is based on the phenomenon of sonoluminescence, which is the emission of light by imploding bubbles in a liquid when exposed to sound waves. Bubble fusion is proposed to generate energy and neutrons by fusing atoms of hydrogen isotopes, such as deuterium or tritium, inside the hot and dense core of the collapsing bubble.
Bubble chambers
Bubble chambers are devices that are used to detect and visualize subatomic particles and their interactions. Bubble chambers consist of a sealed container filled with a superheated liquid, such as hydrogen or helium. When a high-energy particle passes through the liquid, it creates a trail of tiny bubbles along its path by boiling the liquid. The bubble trail is then recorded by cameras or sensors for analysis.
What are the applications of bubbles?
Bubbles have many applications in various fields and domains, such as medicine, engineering, nature, and art. Here are some examples of how bubbles can be used for different purposes:
Bubbles in medicine and health
Contrast agents
Contrast agents are substances that enhance the contrast and visibility of internal structures in medical imaging techniques, such as ultrasound, X-ray, MRI, or CT scan. Contrast agents can be made of microbubbles or nanobubbles that are injected into the bloodstream or other body fluids. The microbubbles or The microbubbles or nanobubbles can reflect or scatter the sound waves, X-rays, or magnetic fields, making the organs, tissues, or vessels more visible and distinguishable. Contrast agents can also carry drugs, genes, or markers to target specific cells or regions for diagnosis or treatment.
Lithotripsy
Lithotripsy is a medical procedure that uses shock waves to break up stones in the kidneys, bladder, or ureter. The shock waves are generated by a device that emits high-intensity pulses of ultrasound or electromagnetic waves. The shock waves create bubbles in the liquid surrounding the stones, which then collapse and produce powerful jets of water that hit and fragment the stones. The broken pieces of the stones can then be passed out of the body through urine.
Wound healing
Wound healing is a complex process that involves inflammation, tissue formation, and remodeling. Wound healing can be enhanced by applying bubbles to the wound site. Bubbles can provide oxygen, nutrients, and growth factors to the wound tissue, as well as remove bacteria, debris, and dead cells. Bubbles can also stimulate blood flow, angiogenesis, and collagen synthesis, as well as reduce pain, swelling, and infection.
Bubbles in engineering and technology
Inkjet printing
Inkjet printing is a method of printing images or text on paper or other materials by spraying tiny droplets of ink from a nozzle. Inkjet printing can use two types of technologies: thermal inkjet and piezoelectric inkjet. Thermal inkjet uses heat to create bubbles in the ink chamber, which then push the ink droplets out of the nozzle. Piezoelectric inkjet uses electric pulses to deform a piezoelectric crystal, which then creates pressure waves that eject the ink droplets from the nozzle.
Ultrasonic cleaning
Ultrasonic cleaning is a technique of cleaning objects or surfaces by using high-frequency sound waves to create bubbles in a liquid. The bubbles then implode and produce intense shock waves that dislodge dirt, grease, oil, or other contaminants from the object or surface. Ultrasonic cleaning can be used for various applications, such as jewelry, dental instruments, surgical tools, lenses, electronic components, and industrial parts.
Microfluidics
Microfluidics is a field of science and engineering that deals with the manipulation and control of fluids at the microscale or nanoscale. Microfluidics can use bubbles as actuators, sensors, mixers, pumps, valves, or reactors in microfluidic devices or systems. Bubbles can be generated, transported, merged, split, sorted, or dissolved in microchannels or microchambers by using electric fields, magnetic fields, acoustic fields, thermal fields, or chemical reactions.
Bubbles in nature and environment
Whale bubbles
Whale bubbles are bubbles that are produced by whales for various purposes. Some whales use bubbles as a hunting strategy by blowing bubble nets or curtains to trap or confuse their prey. Some whales use bubbles as a communication tool by blowing bubble rings or streams to signal their location or intention. Some whales use bubbles as a play behavior by blowing bubble clouds or bursts to interact with other whales or humans.
Bubble nests
Bubble nests are structures that are built by some aquatic animals using bubbles and saliva. Bubble nests are used for mating and breeding purposes by providing a safe and stable environment for the eggs and offspring. Bubble nests are commonly made by some species of fish, such as bettas, gouramis, and catfish. Bubble nests can also be made by some species of frogs, spiders, insects, and snails.
Bubble algae
Bubble algae are a type of algae that have spherical or oval-shaped cells that are filled with water or gas. Bubble algae can be found in marine or freshwater habitats, Bubble algae are a type of algae that have spherical or oval-shaped cells that are filled with water or gas. Bubble algae can be found in marine or freshwater habitats, such as coral reefs, ponds, or lakes. Bubble algae can have various colors, such as green, red, or brown.

FAQs
Here are some frequently asked questions about bubbles:
How long do bubbles last?
The lifespan of a bubble depends on many factors, such as the type and thickness of the film, the size and shape of the bubble, the temperature and humidity of the air, and the presence of dust or other particles. A typical soap bubble can last from a few seconds to a few minutes before it pops.
Why do bubbles pop?
Bubbles pop when the film becomes too thin or too weak to hold the gas or air inside. This can happen when the film evaporates due to heat or wind, when the film drains due to gravity or pressure, or when the film breaks due to contact with a solid surface or another bubble.
Why do bubbles have colors?
Bubbles have colors because of the interference of light waves that reflect from the inner and outer surfaces of the film. The colors depend on the thickness and angle of the film, as well as the wavelength and intensity of the light source. The colors change as the bubble moves or ages.
How big can bubbles get?
The size of a bubble depends on the amount of gas or air that is enclosed by the film, as well as the strength and elasticity of the film. The bigger the bubble, the thinner and weaker the film becomes. The largest soap bubble ever recorded had a diameter of 108.27 feet (32.99 meters) and was created by Steve Langley in North Carolina in 2019.
Can bubbles be square or other shapes?
Bubbles can be square or other shapes if they are constrained by a frame or a container that has that shape. For example, if we blow a bubble inside a cube-shaped frame, we will get a cube-shaped bubble. However, if we release the bubble from the frame, it will revert to its spherical shape. 44f88ac181
