Bubble diffusers aerate wastewater to promote the growth of beneficial bacterial enzymes that break down waste solids. They consist of perforated tubes, plates, or discs that generate bubbles when air is pumped through them. The size of the bubbles affects efficiency. Aeration is crucial for efficient solids removal, but it consumes a significant amount of […]
The spirit level is an ancient tool used to determine straight or plumb lines. It contains a liquid, often ethanol, and a bubble that should be centered between two lines. Laser levels are becoming popular, but accuracy is important in construction and engineering. The spirit level is a very old tool, used by carpenters, bricklayers, […]
A bubble pump uses thermal energy to lift fluids without mechanical energy. It consists of a tube with an inlet in a lower tank and an outlet in a higher tank. Bubble pumps are reliable and cost-effective but not suitable for high-pressure applications. They are used in aquaculture, solar water heaters, and refrigeration cycles. A […]

A bubble echocardiogram uses ultrasound and tiny air bubbles to check for abnormal blood flow through the heart, revealing defects that may require surgery or other treatments. It is often used to diagnose heart defects in young children with symptoms such as shortness of breath or abnormal heart sounds. Patients should not panic if a […]
Bubble sort is an algorithm that sorts lists by swapping and comparing items. It is most useful for small lists, but can be optimized by entering the largest items early in the process. Other comparison sorting algorithms include quick sorts, merge, cocktails, and loops. The caret algorithm is a more efficient alternative to bubble sort. […]
Bubble memory is a non-volatile computer memory that stores data using magnetic bubbles. It was invented in the 1970s and was marketed by several companies, but it was eventually discontinued due to its high production costs, slow operating speeds, and bulky size. Although it is no longer used in modern computers, it is still used […]
Hubble bubble is an English dish made from leftover meat and vegetables, often including potatoes, cabbage, carrots, peas, and Brussels sprouts. It is a variation of bubble and squeak, with the addition of baked beans and tomato sauce. The dish originated in the early 19th century and became popular during WWII. It can be made […]

Superbubbles are formed by multiple closely spaced stars dying, creating bursts of energy and stellar winds that heat gases to high temperatures. Researchers have identified them as the source of cosmic rays and use them to track the formation and death of star systems and learn more about the universe. Images of superbubbles are produced […]
The bubble chamber, invented by Donald Glaser in 1952, is a device used in physics to detect charged particles by creating a trail of bubbles that can be photographed. While it was once prevalent, it is now rarely used due to drawbacks with high-energy particles. However, bubble chamber images are still useful for educational purposes. […]
Bubble wrap was initially created as three-dimensional wallpaper but ended up being used as a packing material for fragile objects. Sealed Air Corporation owns the trademark and offers stress-relieving bubble wrap, as well as iBubble wrap that cannot be opened.
