In 2019, Young Minds organised the 1^st video contest for student chapters. Video was supposed to explain some physical phenomena in an interesting way and popularise science. The award ceremony took place during 8^th Young Minds Leadership Meeting in Erlangen and the winner was chosen out of seven chapters from University of Valladolid, University of Warsaw, University of Strathclyde, Università degli Studi di Napoli Federico II, National Institute of Laser Enhanced Sciences, Humboldt University of Berlin, Faculty of Natural Sciences and Mathematics in Skopje and Yerevan State University.

The prize was awarded to the Young Minds Section from the University  of Warsaw for a video entitled How to make a Jelly Fibre. The video presents an entertaining way of explaining total internal reflection using grocery products and a laser pointer. The jelly fibre experiment was also presented by the section during the biggest science fair in Poland  that took place on 11^th of May  2019 at the National Stadium in Warsaw. The fair is an annual event that hosts around 100 thousand visitors. University of Warsaw YM Section is proud to be part of the Science Picnic for several years now.
