The beauty of the Lab of Luxury Kit lies not only in its end product, but also in its educational value for growing minds. “The Lab of Luxury is a science kit that allows girls to create make-up,” Bill Rayment, owner of Toy Crossing in Harbor Beach, Mich., told TDmonthly. Yet it also allows girls to learn the science behind the make-up they wear. This kit provides components such as citric acid and sea salts to make products as various as fizzing bath balls and glittery lip gloss.
