Magic sticks

The motes in this stick do not fall down in accelerated motion as it usually happens. The small stars and motes move in uniform motion, the former up and the latter down.

The small stars move up as a result of movement of the liquid displaced by the falling motes. The swirling movement is the consequence of turbulences in the liquid. The liquid is dense and has high viscosity; the beads fall down very slowly, in uniform motion, and the turbulences move the stars up.

A similar kind of motion can be observed when flakes of snow fall and there is no wind. The measurements of the uniform settling of tiny oil-drops charged during atomizing brought Millikan the Noble Prize (not for atomizing the droplets but for measuring the electron charge).
