I haven't opened it, but I think the instructions are in English. STEM Kit Start your own geology lab at home: Grow your own crystals with Discovery's 12-piece exploration lab. This all-inclusive crystal growing kit includes everything you need to start creating your own geological formations. No two crystals are the same: Crystallization occurs naturally when liquids cool and solidify, and atoms bond in different ways. This establishes a unique pattern each time a crystal is created. A perfect example of this is the uniqueness of snowflakes. Grow crystals in different shapes and sizes: Create different colors, shapes, and forms with the crystal growing kit. With the included molds, you can grow unique shapes in three different colors that you'll be proud to display. Discover your destination: Take reality to another level with fun and educational toys. You can explore space, fly through the cosmos, walk through the desert with animals, or run away from dinosaurs. Play, learn: At the intersection of inspiration, curiosity, and STEM-based education, our toys stimulate the imagination and promote the development of science, technology, engineering, and math skills.
