Jiří Vlach, a trained materials chemist, who instead of making a mess in the lab decided to show the beauty of natural science to everyone. And so for many years now he has been travelling to schools, companies and public events to perform science shows and pass on his enthusiasm for science. When he's not appearing on the other side of the Czech Republic, you'll find him at home in Brno, where in his spare time he creates new experiments, plays about with electronics, his 3D printer and video games, and thinks up silly jokes...

Lenka Karpísková graduated in physical chemistry and although she spent several years in research, she always preferred talking to people about science than working in a lab. And so she began to focus on popularizing natural science, demonstrating experiments, and spreading her enthusiasm. She loves putting on science shows for children as she also has a child-like joy from discovering the world - but mainly because children laugh the most at her jokes. When Lenka is not popularizing science then it's likely she'll be popularizing science anyway - for example, at camps and lectures. If she really does have some free time, she watches daft videos at home in Brno, plays video games, and tries to do yoga.
