Unchained Reaction (2012)

The six-part series, which pits two teams of varying backgrounds - artists, rocket scientists, animatronic specialists, engineers and even your average Joes - against each other to build an elaborate chain reaction contraption on a massive scale. The teams are provided with identical sets of tools and materials and given five days to complete a series of mechanisms based on a specific theme. Per the network, "refined mechanical movements, pyrotechnics and large-scale destruction are encouraged." At the end of the the five days, Savage and Hyneman are joined by a new guest judge to review the installations and pick a winner.
