- The illustrated instructions explain the experimental process and provides first insights into chemistry.
- This Kosmos explorer set is a magical gift for children aged 10 and up and combines fun with knowledge.
A mysterious, magical glow in the nursery.
With this Kosmos experiment set, children from 10 years become successful crystal growers. The instructions show them in simple steps how to grow sparkling crystals from alum powder. The home-grown crystals are applied to the enclosed large rock crystal and get a bath in a solution of glow-in-the-dark dye. So the beautiful crystal artwork begins to grow and shine.
But how are crystals actually created in nature and where is noctilucent dye used in everyday life? All this reveals the instructions.
Makes chemistry fun!
