S17E10: Heather Gems, Instant Film, Beet Sugar, Electric Roadsters

Dried heather stems are dyed, bundled with resin and compressed into patterned blocks that can be cut and polished into jewellery. Photosensitive layers and chemical pods are combined into instant film, sugar is extracted and crystallized from sliced beets, and battery packs and electric drivetrains are installed in lightweight roadsters.
