Grönlund-Nisunen Spring Field, 2012
Coil springs, solenoids, control unit, electric leads, attachments
Approx. 400 x 300 x 300 cm, height variable
A total of 50 long coil springs are stretched vertically between the floor and ceiling in an 8 x 8 grid. On the floor next to each coil spring is a solenoid. An 8 x 8 grid made of brass wire was stretched along the floor, in line with the grid of coil springs. The brass wires are connected to a power supply via a control unit. The wires stretched in one direction have a positive charge, while those stretched at right angles to them have a negative charge. The control unit randomly momentarily turns on the electricity to one positive wire and one negative wire at a time. If there is a solenoid where the two wires cross, it is turned on and hits the coil spring, making it resonate. The springs continue to resonate for some time, keeping the whole installation vibrating. The sharp clicking sounds made by the solenoids produce a random, but clear rhythm.
