You will not believe how this noise is created! By cotton balls! Yes! This strange sound is produced by cotton balls pounding on the inside of an abandonned tank, the ZIMOUN TANK, situated in Dottikon, Switzerland.
This permanent sound installation was constructed by Swiss artist Zimoun in 2013 in a rusty and abandoned toluene tank.
The 329 cotton balls, powered by small DC motors, pound in an absolutely hypnotizing rhythm against the white and eerie tank. I love it!
