The kit comes with everything you need to get started, including an instruction sheet to take you through step-by-step instructions on how to get your crystal experiment underway.
The crystal will take about seven days to grow, whereupon you can take it out of the wet solution and allow to dry. The crystal will grow differently every time due to varying conditions such as temperature and humidity. Why not get a few and experiment under different conditions to note any changes in shape and size!
Each pack makes a single colour of crystal. Colours will vary.
Recommended for ages ten and over. Not suitable for children three years and under.
