Altered deep-seal water entry behavior of a sphere by a neighboring sphere and/or solid boundary

We investigate the anti-symmetry cavity formation of the deep-seal water entry of two spheres or a sphere and a neighboring solid wall. The breakdown of symmetry causes variation in the cavity sealing (deep-seal) time and the tilted formation of the Worthington jets. A curious observation of cylindrical bubble columns connecting upper and lower halves of the cavities forms after the collapse event is also reported. The phenomenon can be analytically modeled using a potential flow assumption, which can predict the delayed deep-seal times from experiments.
