Unchained Reaction Summary

Adam Savage and Jamie Hyneman from MythBusters serve as judges for two teams of varying backgrounds pitted against each other to build an elaborate chain reaction contraption. But they're not creating a mere string of dominoes - teams must utilize ingenuity, innovation and know-how to build contraptions on a massive scale.

Each week, two teams made up of artists, rocket scientists, animatronic specialists, engineers and even your average Joe, are provided with identical sets of tools and materials and given five days to complete a series of mechanisms based on a specific theme. It's the ultimate build-off pressure cooker, where refined mechanical movements, pyrotechnics and large-scale destruction are encouraged. Making a refrigerator a pendulum? Catapults? Flying saucers? Guillotines? Anything goes as long as they trigger the next link in the chain.
