Mundo Aventura theme park in Bogota, Colombia, has launched the 'Scream to Go ", in collaboration with the communication agency DDB Colombia. In the most extreme attractions, visitors have a headset to record their screams. Each scream is then transferred to a sound device placed under the lid of a glass jar. You just have to open the jar to let out a terrible cry. For 20 dollars, honestly this is one of the most useless idea I have ever seen ! Seriously you need a communication agency for doing that ? Are you kidding me ?
