New Concentrate Formula - Makes over 7 liters (2 gallons) at a fraction of the cost!
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 it's a concentrate that makes over 7 liters (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 visualize. Pearl Swirl is safe and fun to add to many liquids to create a pearly-white effect. Recommended for children ages 4 and up.
- Pearl Swirl Concentrate - 4 oz (120 mL) bottle

How Does It Work?
You’ve undoubtedly seen Pearl Swirl in shampoos, lotions, cosmetics or even water toys. Pearl Swirl contains suspended microscopic particles that make it easy to visualize currents and the flow of a liquid.
What Does It Teach?
Demonstrate ocean currents, aerodynamics, turbulence, convection, erosion, and other movements of nature that are difficult to see. This pearly-white, water-based suspension can be colored with a few drops of food coloring to make it even more effective. Simulate oceanic and atmospheric patterns that will encourage your students to experiment. A science activity guide provides great ideas for demonstrations and science fairs.
- Add 1 tablespoon of Pearl Swirl concentrate to a 1-liter soda bottle filled with water.
- Add a few drops of food coloring to spice things up (blue makes an excellent ocean color)
