Every so many months, our fellowship enjoys the challenge and fun of building something new. This past month, we attempted balloon-powered vehicles! Each team designed and built their own vehicle with an array of cartons, lids, straws, tubes, and other odds and ends. Everyone had different ideas about getting the most mileage out of their balloons. After an hour or so of construction, we lined up our wheels and let them fly. The surprising results were not only fun but also instructive reminders on some of the basic principles of physics.
