On April 28th it was time again, Future Day. Also this year 18 students visited us, who took over the laboratory workplaces for the morning. Dressed in lab coats and goggles, the little researchers practiced, under guidance, various techniques to get to know working in the lab. The highlight was of course the common ice cream, the ice was made by ourselves. For cooling, liquid nitrogen was used, which was previously known in small experiments and demonstrations.
