Description

In this one-of-a-kind chemistry kit, you will make a clear solution and watch it change to amber, then to blue-purple and back to colorless. Watch as it amazingly repeats the color cycle again and again! Discover the chemistry behind the Briggs-Rauscher Oscillating Reaction. Ages 12+ with adult supervision. Contains malonic acid, manganese sulfate, sodium iodate, sodium thiosulfate, sulfamic acid, starch solution, wooden rack, pipet, stirrers, spoon, small scoops, cups, MSDS and instructions. Hydrogen peroxide (3 %) is required, but not included. The REGULAR KITS (singles) include enough materials for repeating each experiment two to three times. The larger CLASSROOM KITS contain five times the materials of the single kits, enough for a five STATION CLASSROOM SETUP that can be REPEATED APPROXIMATELY three TIMES.
