The experiment became a popular way to illustrate the principles of air pressure, and many smaller copies of the hemispheres were made, and are used to this day in science classes. Reenactments of von Guericke's experiment of 1654 are performed in locations around the world by the Otto von Guericke Society.
Tromboning is a type of situation that occurs when data is transferred through a path that goes to a large exchange node and back, much in the way that the path of the sound waves inside a trombone can be elongated by extending the trombone's slide, despite the air entry and exit points remaining the same.

Experiments might be categorized according to a number of dimensions, depending upon professional norms and standards in different fields of study. In some disciplines (e.g., psychology or political science), a 'true experiment' is a method of social research in which there are two kinds of variables.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
A group of students at Ransom Everglades High School in Coconut Grove will see their science experiment launched on a Blue Origins rocket, as part of a program sponsored by NASA.
"Tromboning" involved holding a small object at varying distances from one's eyes, inhaling as it was moved in and exhaling as it was moved out. The program's manual stated, "Tromboning exercises the focusing mechanism, improves control of the extraocular muscles , and stimulates the flow of nutrients inside the eyes".
Experiments with the trombone section included Richard Wagner's addition of a contrabass trombone in Der Ring des Nibelungen and Gustav Mahler's and Richard Strauss' addition of a second bass trombone to the usual trio of two tenors and one bass. The majority of orchestral works are still scored for the usual mid- to late-19th-century low brass ...
