We are among the honorable group of winners of the Coca- Cola competition for a spectacular piece of art made of COCA-COLA bottles. Together with the creative studio THIS (thisiscreative.eu) we designed a Musical Instrument, which was appreciated and noticed by an international jury. We used the acoustic properties of glass bottles and a bicycle drive for its design. As the user is pedaling, it puts the elements in motion and influences the tempo of the melody played. The construction uses 240 glass bottles of Coca-Cola.
