Build a long cantilevered spaghetti beam
I bag of spaghetti per patrol, 2m of masking tape per patrol
Use the masking tape to join spaghetti together (piece by piece, or 5, 4, 3, 2, 1 pieces or how they like). Using one hand to hold one end on the edge of the table, put as long as possible joined spaghetti over the edge without it touching the floor. Leader to measure, at table height, distance between edge of table and length of spaghetti. Fairly easy to get it over 1m long, very difficult to exceed 2m.
