FROZEN WATER FALLS, DEVIL STICKS, FLOWER STICKS, JUGGLING

The manipulation of the devil stick (also devil-sticks, devilsticks, flower sticks, bâtons fleurs, stunt sticks, gravity sticks, or juggling sticks) is a form of gyroscopic juggling or equilibristics, consisting of manipulating one stick ("baton", 'center stick') between one or two other sticks held one in each hand. The baton is lifted, struck, or stroked by the two control sticks ('handsticks', 'sidesticks', or 'handles'), stabilizing the baton through gyroscopic motion.[1]

Manipulating devil sticks is one of the circus arts and is sometimes called devil-sticking, twirling, sticking, or stick juggling.
