This is a school exrecice we did some weeks ago. The exercice was about to create a boomrang card based on a simple subject: teenagers' alcohol drinking.
The basic idea: nowadays every teenager wants to be absolutely cool...what "better" way for them to drink too much alcohol and becoming drunk as hell to be a "funny outsider" hyper cool person.
The concept: the concept here is quite simple. The bunch of bottles you see represent a bunch of teenagers. On the bottles you can read the pourcentage of alcohol you have in it but the bottle in the center has a zero pourcentage. So the center bottle / the center teenager decided to do not drink alcohol.
The message: the message writen at the bottom means "Amusing itself begins by drinking in a different way too" and on the back of the card you have the text explaining the purpose of the campain and so forth. The fictional campain is called "Do ya see your self when ya're drunk ?".
