DescriptionThe Bioluminescent Bio-Orb is a hand-blown glass sphere filled with bioluminescent PyroDinos (dinoflagellates). The Bioluminescent Bio-Orb will produce natural light (bioluminescence) at night when gently swirled. The Bio-Orb shipment should be opened upon arrival, and the PyroDinos (living algae) should be put in a location that receives low to moderate light during daytime hours. PyroDinos will only light up at night, in the dark when gently swirled. PyroDinos will not light up during daytime hours!
