The motion of particles of different properties and sizes in ALF ultrasonic cavitation structure is investigated experimentally with high-speed photography. Particles tend to transport along the bubble chain and move towards the focus repeatedly and predictably in ALF cavitation structures. Particles at the focus aggregate and separate alternately over time. https://www.jmannino.com/mega-pick-NFL-San-Francisco-49ers-Zone-Block-iPhone-14-Pro-MagSafe-Case-p80213-quick-pick/
