Mesons produced in a bubble chamber

A bubble chamber is a pool filled with a liquid (typically hydrogen) such that its molecules are ionized to the passage of a charged particle, thus producing bubbles. In this way the trajectories of the particles are visible and it is possible to study the various decays⁽²⁾.
The bubble chamber was invented by Donald Glaser⁽¹⁾ in 1952, who win the Nobel Prize in 1960.
