Measure pH, do science magic, and learn about indicators, acids, and bases! Use with Polyvinyl Alcohol (PVA) and borax solutions to make red, white, blue, and purple slime. Phenol Red is commonly used to test pH in spas and swimming pools. Bromthymol Blue is used to make Cub Scout's favorite colors (blue and gold), and Girl Scout's and four H Clubs' favorite color (green). Both are used in elementary science experiments and have many uses in biology.
