Plasma in water is capable of forming bubbles because streamer gas channels formed by the discharge show the same process of cavitation bubble dynamics, such as growth, shrink, collapse, rebound, and fragmentation. This paper introduces the formation of fine/ultrafine bubbles, generation of hydrogen gas in bubbles, an estimation of the amount of electrical charge in bubbles, and a method for distinguishing gas bubbles from solid particles.
