Why is it contagious when someone itches, rashes are infected and where do lice live when they do not live in the hair are some of the questions the children ask in the studio. We get to follow Alicia who gets to do a spot test to see if she is allergic to something and Nellie who got mollusks. It will be a skin experiment and we will show how to get rid of lice. Participants: Pediatrician Petter Borna and the orchestra "Prickarna".
