The art of crystallisation – a global experiment

Collaborate with thousands of students from around the world by taking part in this experiment.

Follow the instructions to grow your own crystals, analyse the results and post your local data. By taking part we want you to help us answer the question: what are the best conditions for growing the biggest crystals?

The global experiment will remain open so you can participate anytime.
