The Marshmallow Challenge is a reliable activity for quickly building team connection and energy. Provide teams with spaghetti, tape, string, and a marshmallow. Their task: construct the tallest freestanding structure. This exercise fosters immediate collaboration, communication, and a shared sense of accomplishment. It is an effective way to kickstart problem-solving dynamics and establish rapport, making it ideal for new teams or re-energizing existing ones. Use it early in a workshop to set a collaborative tone.
