Episode overview
Steel columns, steps and railings are measured, shaped and welded into space-saving spiral staircases. Yeast dough is mixed, divided and baked at high temperature so steam inflates each pita; metal tubing is bent and welded into exhaust headers; and crushed limestone mixtures are cast and finished as decorative artwork.
