Another artwork by Kaufmann which also involves sound produced by spinning beverage cans is his “Pray Wheel Nr. 4”…
Prayer Wheel Nr. 4
there is a coca cola and a pepsi cola can rotating on 12V fans. behind the cans there is a IR-Sensor for each of the can. the captured signal is amplified and the 2 sounds are subtracted from each other and you can hear it on the headphone.
what is left if the sound of the two deadly enemies is subtracted?
hmm i would say a warm prayer wheel sound of peace.
Whether you view the Coke/Pepsi dichotomy as the classic example of capitalist competition or a false equivalence of consumer goods, Kaufmann is not the only artist to have focused on the supposed duality of cola choices.
Fact is, I think we may have enough material here for an entire “cola wars week.” Starting right now.
