What are the best conditions for growing the biggest crystals?

The Royal Society of Chemistry and the International Union of Crystallography announce the Global Experiment 2014 "The art of crystallisation" to try to find the best conditions for growing crystals.

Collaborate with thousands of students from around the world. Follow the instructions to grow your own crystals, analyse the results and post your local data.

The Global Experiment 2014 is aimed at students aged between 7 and 16 years, working in consultation with their teachers. It will remain open for the 2014-2015 academic year.
