Using a box of spaghetti, a roll of tape, and a tabletop, can your team work together to create a cantilevered structure? The structure should cantilever as far as possible over the edge of the tabletop without touching the floor.
This engineering challenge is courtesy of mentalrobics. If your team needs the incentive, up the ante with points - offer one point for every inch the structure extends beyond the edge of the table. Make it even more difficult by adding a time limit.
