One of the most popular types of entertainment in Brazil is karaoke. Amateur singers and young people frequent these bars after work and on weekends.

Bar Aurora & Boteco Ferraz decided to attack the problem with something young people can’t dodge: fun. We created the world’s first microphone breathalyser and invited people to sing karaoke. Once on stage, we took them by surprise. At the end of each song, instead of showing their score, we showed their alcohol blood level.

All the singers received a real proof that they were not capable to drive with all their friends and people at the bar as witnesses. They received a card with their alcohol blood level and a drunk driving message. They took pictures and shared it with their friends. The message quickly spread on Twitter and Facebook through users around the world. Bar Aurora & Boteco Ferraz received the attention they wanted and the most importantly, people realised that even though they feel they can do anything after drinking, it can never be driving.
