13. Pétanque Balls, Biologic Medicines, Asphalt Pavers, Basque Espadrilles

Steel hemispheres are formed, welded together, heat-treated, engraved and balanced to produce pétanque balls. Living cells are cultivated under controlled conditions before the resulting biologic medicines are purified and formulated; conveyors, augers, engines and adjustable screeds are assembled into asphalt pavers; and coiled jute soles are stitched to fabric uppers to make traditional Basque espadrilles.
