  In the Ellis-Bronnikov wormhole (WH) metrics the motion of a particle along
curved rotating channels is studied. By taking into account a prescribed shape
of a trajectory we derive the reduced $1+1$ metrics, obtain the corresponding
Langrangian of a free particle and analytically and numerically solve the
corresponding equations of motion. We have shown that if the channels are
twisted and lag behind rotation, under certain conditions beads might
asymptotically reach infinity, leaving the WH, which is not possible for
straight co-rotating trajectories. The analytical and numerical study is
performed for two and three dimensional cases and initial conditions of
particles are analysed in the context of possibility of passing through the WH.
