These variables typically include, but are not limited to, the following: Often tricks require manual dexterity, coordination, and fine timing to accomplish.
Reels - refer to any number of wall-plane oriented tricks in which the planes move from in front to behind the poi-spinner in an alternating fashion.
The intended effect is that the hand would stop the poi traveling on the unit-circle's tangent and thus canceling its centripetal motion.
Extension - also known as "long-arm", refers to a specific type of hybrid-timing where the poi-head and the spinner's hand share the same directionality in a manner such that they form two concentric circles.
This type of move involves the spinner's arm being fully extended as the hand follows the unit circle.
Snake - refers to any number of tricks in which the poi heads adopt a sinusoidal path as a result of the hands moving along or across the axes.
Melt-down - refers to any number of tricks involving each hand moving from a crosser to a waist-wrap position in a continuously alternating fashion.
The buzzsaw refers to a class of tricks in which the poi planes are joined in such a way as they spin in a parallel fashion to the direct heading of the spinner.
Fountain refers to a class of tricks in which the poi change direction of spin in relation to the orientation of spinner.
Thru-wrap - refer to a class of tricks in which the poi wrap with a body part or with each other in such a manner as to not change the direction of spin.
Air-wrap - also known as a tangle, refers to a through-wrap in which the poi are wrapped with each other thus changing their respective centers of gravity to the point of intersection, typically for one rotation.
[6] Dodging Daggers - refers to a type of reel by which the center of the poi's gravity passes between the spinner's legs.
Contact poi are often constructed in such a manner as to provide the handle with additional weight that serves as a counterbalance for the poi-head.
