About the Algae:  Spirulina is the common name of the cyanobacteria Arthrospira plantensis.  It is commonly found all around the world making it one of the rare endemic strains of the Earth.  It is also an extremophile for pH, it does very well at pH ranges up to 10.5.  Spirulina is commonly used as a food or nutraceutical for humans and animals.  It contains the pigment phycocyanin which is a water soluble phycobilin or photosynthetic protein.  It is shaped as a beautiful helical colony called a tricome.  

Forget genies, discover the magic of photosynthesis with algae in a bottle!  This product can be used to resupply your stash or continue the experimentation you began with our many kits and experiments.  If you need more than just algae, consider our Spirulina Culture Kit which contains everything you need to grow a laboratory-grade culture at home or at your desk. It is so much fun to grow, and easy to harvest (see Spirulina Farming Kit to grow your own!). It's a great model organism to teach photosynthesis and aquaculture.
