Unchained Reaction

It was judged and executive-produced by Adam Savage and Jamie Hyneman, best known for hosting the science entertainment series MythBusters.

[1][2] The show pits two teams of various backgrounds against each other to build an elaborate chain reaction contraption (sometimes also referred to as a "Rube Goldberg" machine or device).

Teams are provided with identical sets of tools and materials and are given five days to construct a series of mechanisms based on a predetermined theme.

Midway through each week, the teams are provided with a surprise "missing link" item that they must add to the middle of their machines.

[3] In the announcement, Savage said he and Hyneman wanted to create a show "that puts the process of problem-solving and ingenuity front and center".
