The document outlines instructions for a team building activity called the Marshmallow Challenge. Teams of 2-5 people will have 18 minutes to build the tallest freestanding structure they can using only 20 sticks of spaghetti, tape, string, scissors and a marshmallow. The goal is for the entire marshmallow to be on top of the completed structure. Lessons on prototyping, diverse skills and incentives will be discussed based on the results of the challenge.
