Black Pearl is a kinetic sculpture made completely from recycled found metal objects. "Kinetic" means energy in motion. The top part of the sculpture balances on a single pinhead made from a tungsten rod resting on the bottom half of the piece. The two halves are only connected by gravity. There is less than 1/64th of an inch joining the two halves allowing almost zero friction between the pieces. The top piece is very wide and heavy, allowing it to spin for such a long time.
