The process of bubble generation, and the subsequent growth and collapse of the cavitation bubbles, results in very high energy densities and in very high local temperatures and local pressures at the surface of the bubbles for a very short time. The overall liquid medium environment, therefore, remains at ambient conditions.
Magic 8 Ball. The Magic 8 Ball is a plastic sphere, made to look like an oversized eight ball, that is used for fortune-telling or seeking advice. It was invented in 1946 by Albert C. Carter and Abe Bookman and is currently manufactured by Mattel. [1] The user asks a yes–no question to the ball, then turns it over to reveal an answer that ...

A bubble chamber is a vessel filled with a superheated transparent liquid (most often liquid hydrogen) used to detect electrically charged particles moving through it. It was invented in 1952 by Donald A. Glaser, [1] for which he was awarded the 1960 Nobel Prize in Physics. [2] Supposedly, Glaser was inspired by the bubbles in a glass of beer ...

Microbubble. Microbubbles are bubbles smaller than one hundredth of a millimetre in diameter, but larger than one micrometre. They have widespread application in industry, medicine, [1] life science, [2] and food technology. [3] The composition of the bubble shell and filling material determine important design features such as buoyancy, crush ...
Sonoluminescence is the emission of light from imploding bubbles in a liquid when excited by sound. Sonoluminescence was first discovered in 1934 at the University of Cologne. It occurs when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly, emitting a burst of light.
