Pearl Swirl™ Fluid
Pearl Swirl™ Fluid is the secret ingredient that gives some shampoos that pearly-white look or creates wave currents in some shake-up water toys. In scientific terms, Pearl Swirl is a rheoscopic fluid, but this is a concentrate that makes 2 gallons! When added to water (or other liquids), it allows you to see the movement or currents in the liquid. This pearly-white, water-based suspension is safe and non-toxic and excellent for teaching units on ocean currents, aerodynamics, turbulence, convection, and many other motion effects that are often difficult for students to visualise.
Contains: 113ml bottle of Pearl Swirl™ concentrate to make up to 2 gallons of rheoscopic fluid.
