Why do you not need poop when you sleep, you can get a stomach ache from drinking milk and why you get a hard stomach are some of the questions the children ask in the studio. We also get to follow Emrik during a stressful day in his life. There will be experiments with poop and we will see how constipation in the intestines can be avoided. Participants: The pediatrician Ola Andersson and the orchestra "Magsäckarna".
