Glowsticking is a form of object manipulation or dancing with glowsticks or other glowstick-like objects that share the same qualities: durability, consistency in light, safe to toss around, and the material of which they are made, often a soft and pliant plastic.
Glowsticking is an "umbrella term" describing two broad categories, with the most agreed upon separation being whether it is stringed or not stringed. More importantly, glowsticking has roots in the electronica and rave scenes, and has a cultural paradigm more in common with those scenes than those of other scenes. Some aspects include the culture of non-competitiveness, preferring sharing and performing in accordance with your observer, without any kind of negative statement implied. Because of this glowsticking competitions are frowned upon by most practitioners of glowsticking. Although glowsticking as a field can largely be practiced anywhere, the roots it has with raving has led to the adoption of most of the ideals of the rave scene. In recent days complete glow stick costumes have been created that attach to one's body, the two most popular being from Crayola and Glowstickables.
