see-saw

Takafumi Morita +Yasuaki Kakehi


see-saw is a kinetic installation that uses liquid flow. By moving the liquid inside the seesaw and changing the position of the center of gravity, the inclination of the seesaw changes dynamically. The liquid is controlled by a module based on the electrohydrodynamics (EHD) phenomenon, in which liquid flow occurs when a high voltage is applied to electrodes placed in a dielectric liquid. This creates a silent motion without any driving noise from actuators. One of the etymologies of the word "seesaw" is that it is a repetition of "see" and "saw", hence the name "seesaw". A seesaw visualizes a liquid that continues to move without sound, defying gravity by an invisible driving force. It expresses the "relationship" (Interverse of Things) between the things that surround us.
