Fish Replicas, Siren Systems, Pre-Packaged Sandwiches, Candlesticks

How It's Made – Season 18

Moulds taken from real specimens are used to cast lightweight fish replicas, which are carefully painted to reproduce natural markings. Electronic and acoustic components are assembled into powerful warning sirens, ingredients are portioned onto bread and sealed in protective packaging, and metal is cast or shaped before being polished into decorative candlesticks.
