This is a time lapse of Chloe's blue ribbon San Francisco citywide science fair experiment. A picture was taken every 15 minutes for 13 hours. Each tank was saturated with equal amounts of algae, but only one tank had 42 hungry, native olympia oysters in it. She also tested a variety of biological and chemical measures before and after the experiment. Look for Mimo photo-bombing his way into science about half way through.
