Spaghetti with marshmallows? No, it isn’t a new diet fad! The Explorers were given a challenge: build the highest free standing tower using 20 sticks of spaghetti, 1 yard of tape, and 1 yard of string. They could use as much or as little of the supplies as they felt necessary — but their structure MUST support the weight of one marshmallow. It was really interesting to see the groups working together!
