The Mini Firefly Sphere has green parts that glow in the dark, while the black parts blend into dark surroundings. When tossed around in the dark, it creates the illusion of fireflies. This Hoberman Sphere is versatile - it can be thrown, bounced, kicked, spun, rolled, or suspended from the ceiling.
The polymer links allow the sphere to change in volume!
