Our tabletop version of Chain Reaction, a true machine building challenge. Teams need to work together to build a contraption or machine that will accomplish a specific end goal, e.g. erase a whiteboard or staple two pieces of paper together, pop a ballon, etc. The group is given an array of everyday household objects to accomplish their task with. The objective is for each team to work together to ensure that their individual section work and meet all of the assigned requirements, while also making sure that it will trigger and works with the teams’ contraptions on either side of them, and so on, until the overall objective is achieved. There are many robust work-related metaphors that can be drawn out of this program.
