Scientist have proven what we already knew for a long time. Energy drink are really disgusting! And also, bad for your health. They can cause excessive heartbeats, forced insomnia and uncontrolled hyperactivity. This design proposses a clear iconographic warning sign for these symptoms [the people that drink this can't read].
Also, in line with other product that should be banned out of society for health reasons the can design is changed from a branded can to a neutral, blank design with a big warning and only a small brand descriptor to to disencourage purchase.
