Bubble chamber, radiation detector that uses as the detecting medium a superheated liquid that boils into tiny bubbles of vapour around the ions produced along the tracks of subatomic particles. Two of the most important early detecting devices were cloud and bubble chambers. Short online tutorials cover the basic concepts while the experiments you need. Supposedly, glaser was inspired by the bubbles in a glass of beer. Basically, there needs to be a magnetic field acting down through the bubble chamber to allow a particle to have a curved path, since the magnetic field gives it a force perpendicular to its motion.
