Vertical motion of particles in vibration-induced granular capillarity

open access: yesEPJ Web of Conferences, 2017
When a narrow tube inserted into a static container filled with particles is subjected to vertical vibration, the particles rise in the tube, much resembling the ascending motion of a liquid column in a capillary tube.
