Science Dictionary
bubble chamber   (bŭb'əl)  Pronunciation Key 
A device used to observe the paths of charged subatomic particles. A bubble chamber consists of a container filled with very dense fluid that is close to boiling. The moving particles create tracks of bubbles in the fluid that can be photographed and analyzed. Bubble chambers have been largely supplanted in laboratories by more sensitive particle detectors that do not rely on the human eye. Compare cloud chamber.
