For the final project in physics class, students were given 750 flat toothpicks, a spool of thread and some Elmer's glue. With only those materials (and an optional "base" to which they could affix their bridge) they had to make a bridge that would support a 5 lb. brick. The span had to be 12" long, and the "roadbed" had to be 9" off the ground. Here is a sampling of the many creative designs.

Jessica Alderman opted for an arch design. Bonus points for not having a base to secure the bridge! Viewed: 4903 times.	A close-up of Jessica Alderman's bridge Viewed: 2592 times.	A close-up of Jessica Alderman's bridge Viewed: 2405 times.
Evan Greer's bridge has no roadway, but it's good for holding bricks! Viewed: 2882 times.	The strings are in tension, and the cross bar is in compression as they should be. The uprights look like they are encountering a shear force without bricks on top. Viewed: 2664 times.	Lisa Loren's elegant suspension bridge. Viewed: 2575 times.
