🦄 Grow four vibrant crystals inside a magical unicorn terrarium—kids mix seed compounds with hot water in clear growing cups, then watch shimmering crystal structures develop over several days surrounding unicorn figurines for visual delight.
🔬 Encourages hands‑on chemistry and geology learning—children aged 10+ explore nucleation, saturation and growth rate principles as they monitor crystal development and observe varying shapes and colors in each display container.
🌈 Everything included for complete experiments—two unicorn figurines, colored sticker sheet, four sizes of transparent cups, two white crystal powders, three color additives, stirring bowl, spoon and illustrated guide.
🧠 Promotes patience, observation and scientific thinking—kids record observations in steps, compare containers, and learn how temperature, saturation and seed timing affect crystalline outcomes across multiple trials.
🧩 Ideal STEM craft gift that also displays—once matured, crystals stand proudly inside the terrarium tray topped with cover, creating a decorative unicorn-themed science showcase that doubles as room décor.
✅ Made by trusted 4M science brand—safe non-toxic materials, clean setup, durable components and clear instructions enable repeatable, educational crystal experiments with artistic flair.

Step into a world of prehistoric enchantment with the 4M Magical Unicorn Crystal Terrarium Kit—perfect for curious minds aged 10 and above. This complete STEM science set allows children to grow four colorful crystals within a unicorn-themed display tray, creating a mini fantasy landscape over 4–7 days of crystal development.

Each kit includes two unicorn figurines, a colored sticker, four transparent growing cups of varying sizes, two white crystal powders, three colorants, a stirring bowl and spoon. By mixing powders with hot water and adding color seeds, kids initiate crystal formation and observe how temperature, saturation and crystallization stages produce varied shapes, sizes and hues.

As crystals form and reach about 5 cm in width, the terrarium becomes both a scientific experiment and a decorative display. Children hone fine motor skills, sharpen observational reasoning and build patience while tracking growth stages and comparing results across cups.

Designed with safe ingredients and clear, illustrated instructions, this kit delivers polished science learning with minimal mess. Backed by 4M’s reputation, it’s a standout STEM gift that mingles chemistry, geology and unicorn magic in every sparkly specimen.
