Very few things bring people together like music. The Kopparberg summer pack allows you to use the bottle as a musical instrument to produce tunes with friends. These songs can be shared on social media, using the hashtag #MakeMusic. Markings on the side of the bottle show how much drink you need to play a certain note. The bottle also has embossed ridges that can be used to run the stick up and down, creating a scraping sound. By using the Kopparberg bottle as a musical instrument, people can come together to drink and make music this summer.
