The Thames & Kosmos Yummy Rainbow Lip Balm Lab STEM Kit offers a hands-on introduction to the chemistry and biology behind skin care. This educational set allows users to mix and create their own lip balms and glosses using included ingredients that produce strawberry, grape, and banana flavors. The kit comes with cosmetic jars for storing finished products, as well as step-by-step instructions in both English and French.

Designed for curious learners, the lip balm lab focuses on the scientific principles of emulsions, natural waxes, and oils commonly used in cosmetics. The included materials are non-toxic and safe for supervised use, making it suitable for children and teenagers interested in science and personal care. The kit encourages experimentation with proportions and fragrance combinations while explaining how ingredients interact to create moisturizing balms and glossy finishes.

The set is appropriate for home, classroom, or group activities where STEM concepts are explored through creative, real-world applications. It does not claim to replace commercial skin care products or provide therapeutic benefits, but rather serves as an educational tool to understand formulation basics. The bilingual instructions (English/French) add accessibility for diverse learning environments.

All components are sealed and measured for single-use experiments, and the final lip balms are intended for personal use. The kit complies with safety standards for children’s educational products. Its approach balances fun with factual science, without promising specific skin care results or long-term effects.
