Precision timers, locking mechanisms and reinforced housings are assembled into time-delay locks designed to prevent safes and vaults from opening before a programmed interval has elapsed. Brownie batter is mixed, deposited and baked on an industrial production line; automated dispensers separate and release pallets one at a time; and metal frameworks are decorated with carefully cut and polished crystals to create chandeliers.

The show’s own verdict is on its page.
