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.
