Taking part in scientific research doesn't always involve giving blood samples or filling out questionnaires. 80 lucky students at Radboud University in Holland got to spend time watching films, sitting on the sofa and drinking beer, wine or soft drinks. They were taking part in a study into how watching films and adverts featuring alcohol affects people's drinking. Some watched a film with drinking in and commercials featuring alcohol while others watched non-alcoholic films and commercials. The students who saw alcohol on screen drank, on average, 1.5 more bottles of beer than the other group.
