The IUCr Crystal growing competition is open to all schoolchildren up to the age of 18, and aims to introduce students to the exciting, challenging and sometimes frustrating world of growing crystals. Following the great success of the IYCr2014 and 2015 competitions, schoolchildren were invited to take part in the 2016 edition and convey their experiences of growing crystals through a video. An international panel of judges has evaluated the entries based on creativity, aesthetic value, description of working plan and experimental work, clarity of explanations, scientific background and safety. The details of the winning teams can be seen in the table below; all will receive a 'Young crystal growers' certificate and a medal. We congratulate the laureates, and hope you will enjoy watching the winning videos at
