Glowsticking is a form of dance using glow sticks or LED light sticks for a performance similar to poi or firedancing. Glowsticking is a blanket term describing two broad categories of glowsticking, stringed or non-stringed, otherwise described as ‘glowstringing’ and ‘freehand glowsticking’.
Here is a great video of ‘glowstringing’ in action!
