Episode overview

Thick steel plates, internal reinforcement and heavy locking mechanisms are combined to produce doors capable of resisting powerful explosions. Waxes, oils and pigments are blended and moulded into lipstick; sculpted trunks and synthetic fronds become artificial palm trees; and engraved or cast brass plates are polished and finished as decorative plaques.
