The magic of the Color Lab Mixer is in its three scientifically designed chambers. Kids fill the two side-by-side chambers with water, and then add a different Color Splash™ Tablet to each chamber. When they carefully tip the Color Lab Mixer, the two colors spill into the front chamber, creating a third color. The toy includes color wheels, a mixing diagram and 24 assorted Color Splash Tablets. The Color Lab Mixer demonstrates the magic of color mixing, making bath time not only great fun, but a hands-on learning experience as well.
