Launch superhero science adventures with the 4M Disney Marvel Avengers Crystal Terrarium Kit—designed for curious kids aged 5 and above. This enthusiastic chemistry kit allows children to grow a crystal measuring approximately 4.5 cm in diameter within a Marvel-themed display dome.

Inside the kit, children find a packet of white crystal compound, a red colorant packet, a crystal base, mixing bowl, spoon, display cover, Marvel character wrapper and rescue card sheet. After mixing the compound with hot water, children pour the solution into the base and watch as crystalline structures form over time. Results may vary in shape, size and color depending on conditions, providing real science insight.

This fun project encourages STEM learning—kids explore nucleation, solution concentration and crystal morphology through observation and experimentation. The included Marvel-themed cards add extra excitement, blending science with comic-book inspired collectible appeal.

Ideal as a birthday present, classroom experiment or rainy-day discovery kit, this clean, compact set ensures immediate play and easy cleanup. Fully packaged and backed by 4M’s educational standard, children engage in hands-on learning and proudly display their crystal creation under a clear dome.
