Harry, Ron, and Hermione call it Potions Class; we call it Chemistry Class! Wizards in training can follow the storybook manual as they brew up five different drinkable potions. Along the way they'll learn about chemical reactions, polymers, solutions, suspensions, indicators, mixtures, and density. Potions include a fizzing citrus elixir, strawberry "frog's eggs," a color-changing "transmogrification" potion, a slimy chia seed drink, and an "anti-gravity" tonic. The kit includes a plastic cauldron; a magic wand (which serves as a mixing rod and measuring spoon); ingredient packets; three round flasks; a measuring cup; and a 12-page storybook and experiment manual.
