The manipulation of the
devil stick (also
devil-sticks,
devilsticks,
flower sticks,
gravity sticks, or
juggling sticks) is a form of
gyroscopic juggling or
equilibristics, consisting of manipulating one stick ("
baton") between one or two other sticks held one in each hand. The baton is lifted, struck, or stroked by the two control sticks ('handsticks' or 'sidesticks'), stabilising the baton through gyroscopic motion.
