Grow and sustain your own living, glowing marine laboratory! Bring the magic of ocean bioluminescence into your home by cultivating and expanding your own pure colony of Pyrocystis fusiformis, a fascinating marine algae species. Step into the role of a marine biologist by feeding your algae weekly with a nutrient-enriched seawater medium to help it grow. Because these incredible organisms follow a strict internal biological clock, they photosynthesize and recharge during the day, reserving their breathtaking neon-blue glow strictly for their nighttime cycle! A gentle swirl of the vessel after dark triggers a stunning natural light show. Want to see them flash during the day instead? The included logs will teach you how to easily 'flip' their light schedule using a simple lamp or closet setup! It’s an eye-opening activity that beautifully demonstrates cellular circadian rhythms, biological light production, and the science of living cultures. Includes comprehensive instructions and student worksheets.
