Final idea

There will be a group of 18 year olds at the park during their lunch break at college. Someone takes a wispa chocolate out of their bag and they will start talking about Cadburys chocolate. One person will say "Everybody's shouting about Wispa". One person in the group won't understand what they mean, as they will be confused about how you can shout whilst whispering. Another person in the group will explain and talk about the wispa chocolate and ask the confused person to try it. The person tries it and likes it. The screen then changes to a picture of the wispa chocolate bar and the narrator will say the name of the chocolate and the slogan.
