With this indulgent kit, girls can transform a bath into a frothy fizzing sea of color and fragrance. They can make colorful, fragrant bath soaps, fizzers and oatmeal scrub while learning the science behind gels, fragrance and more. This kit “is not about being a stick figure or a beauty queen, but rather about relaxation and learning….While mixing and matching custom fragrances, kids can learn about the science of smell. While whipping up a fizzy bath ball, kids learn about how acids and bases react,” said Elizabeth Rives of Scientific Explorer, who created the kit for the company while still a college student.  Launch date: February 2003.
