Grow crystals
"Growing Crystals"
- New breeding methods! With this experiment box, children can create a sparkling world with even more intense colors overnight or in experiments lasting several days.
- Many shapes and intense colors ensure even more variety and creativity. Small plaster molds are covered with crystalline shells and glittering crystal caves – so-called druses – are created.
- The highlight: A “glow in the dark” dye creates glow-in-the-dark crystals that can be displayed in a treasure chest or used as sparkling decoration.
- The age-appropriate instructions for the KOSMOS experiment kit explain step by step how to safely experiment with the chemicals and provide interesting knowledge about crystals and minerals.
- A creative and exciting way to discover the MINT science of chemistry and a great gift for children ages 10 and up who are thirsty for knowledge.
New breeding methods and a wealth of experimental material – this large crystal growing set from KOSMOS is full of creativity and possibilities! Children aged 10 to 14 can create their own sparkling world: shimmering individual crystals are created overnight, glittering crystal caves are made themselves, plaster figures can be covered with a magical, crystalline cover and, as a highlight, noctilucent crystals sparkle in the small treasure chest.
With clear pictures, the instruction booklet for the experiment kit explains how the miracles are made in various experiments and shows how you can influence the size, colors and shapes of the growing crystals or grow them using a thread.
The follow-up pages of the instructions contain a lot of interesting information about natural crystals. A creative and exciting way to explore the STEM science of chemistry!
