The winning video, called Molecular Clusters, features an original rap song and dance explaining how groups of molecules stick together to form clouds. The trio of research students from the Institute for Atmospheric and Earth System Research at the University of Helsinki, including Jakub Kubečka, Ivo Neefjes and Vitus Besel, won both the physics category and the top prize. They were selected by a jury composed of previous winners and world-renowned artists and scientists for presenting the best combination of science and art, beating 39 competitors and pocketing a cheque for $2000.
