10" FingerLights make everyone in the room a participant, regardless of their physical abilities. That's because when fully inflated they're so responsive that their polyurethane (PU) panels will first stretch around the surface they hit ( a finger, a nose or the top of the head) and then rebound off it. They're so light that they'll literally float on room currents like bubbles. While we. the unique PU panels and solid welds are so strong. FingerLights are sold in pairs, one each of translucent green and purple.
