In particle physics a ‘shower’ is the avalanche of secondary particles produced by an incoming particle with high energy. This production requires the interaction with mass. A shower produced by high-energy cosmic rays usually covers a wide area, on the order of a square kilometer. The secondary particles can be observed by using scintillators. In view of the large area affected and the relatively simple equipment needed, this is an ideal project to involve high-school students and their teachers. Showering can also be observed indoors, on a muchsmaller scale.
