Jamie Hyneman and Adam Savage have fabricated a new TV concept. The Mythbusters guys are partnering for a new Discovery special that takes their talent for building awesomely destructive gadgets and crosses it with kids’ playtime. The result: Dangerous Toys, a one-hour special produced by Hyneman and Savage.

The special takes a kids’ fort-battle game and blows it up with adult-sized concoctions. Hyneman and Savage will interview teens for ideas and build giant versions of child-play favorites — such as a 25-foot couch fort and explosive robotic armies — in an attempt to bring each other down. “It does mean we’re going to have to interact with children though,” Hyneman points out.

The project marks the second Mythbusters-related concept the duo have partnered for on the network. The first was Unchained Reactions, a 2012 reality competition judged by Hyneman and Savage where teams compete to build complicated contraptions.

Dangerous Toys is set to air Saturday, Jan. 11 at 9 p.m. Here’s a teaser video to give you a better idea of the concept:
