Episode overview

Felt hat bodies are steamed, stretched over wooden forms and trimmed into top hats and bowlers. Absorbing collectors, pipes and insulated tanks are assembled into solar water-heating systems; enriched dough is rolled with a sweet filling, sliced and baked into sticky buns; and a thin charged diaphragm is suspended between perforated panels to create electrostatic speakers.
