Jeff Koons focuses on three basketballs hovering in equilibrium in his Three Ball 50/50 Tank (Spalding Dr. JK Silver Series, Wilson Supershot) Skateboard. In his Equilibrium series, Koons received guidance from Nobel laureate physicist Dr. Richard P. Feynman, as Koons strived to achieve permanent equilibrium by suspending basketballs inside water tanks. Presented as a triptych, we see exactly half of each ball submerged below the water and half on top, miraculously floating. However, the balls will remain 50% submerged below the water line but due to vibrations, the balls will move to the left or rights of the tanks. The balls are a philosophical reference to existentialism from the womb to the eternal. © Jeff Koons
