Aligning the plunger.

The task of the workshop was to make the largest diameter sphere feasible without heavy equipment. Inspired by Andy Goldsworthy’s snowballs, the students came up with the idea to cast a beach ball inside of the mold. Heat from the concrete curing bursts the ball, and a spherical hollow is left inside.
