SPAGHETTI BRIDGE BUILDING CODE
1.	The bridge must be built of spaghetti and joints may be joined only by glue sticks of the variety used in hot glue guns (welders).
2.	Draw plans of the bridge to show three views: the view from one end (if you were driving onto the bridge), the view from the side (as if you were looking at the bridge from the river), and the view from the top (looking down from a plane).
3.	When building the bridge, apply glue sparingly only to join the ends of the steel beams or the centers of steel supports which form x's. Welding material may not be used to join a steel beam along the entire length of another steel beam.
4.	The bridge, at all times, may touch only the painted areas on the top of the canyon and the canyon walls.
5.	The bridge must span a minimum distance of 50 cm across the canyon, but may not exceed 58 cm in total length.
6.	The bridge must not exceed a maximum distance of 50 cm above the floor of the canyon.
7.	The bridge must include a decking of tagboard (highway) to provide a solid driving surface at least 5 cm wide but not greater than 7 cm over which a small metal car of the "Hot Wheels" or "Matchbox" variety can pass easily.
8.	The maximum mass of any bridge including the loading platform may not exceed 200 grams.
9.	An "official loading platform" made of 1/8 inch hardboard with a metal hook attached, must be purchased from the steel company. The loading platform must be located at the center of the bridge, immediately below, or above the decking material. The loading platform may not be altered in any way except to facilitate its correct placement at the center.
