 Poi can be performed in the dark to dramatic effect when spinners use poi containing a light source, such as UV-sensitive materials, LED lights, or chemical glow sticks.Glowstringing, or using glowsticks swung from shoelaces, is popular at festivals and raves.It is also noted that while poi focuses on the manipulation of the head (the other side of the cord/chain from where you are holding), glowstringing focuses on the manipulation of the cord.
