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.
