Hard, uncooked spaghetti is useful for a number of crafts projects. This is because it has strength but is also easy to bend and break into smaller pieces, which are necessary for different designs. Small, model bridges are often made with uncooked spaghetti, creating excellent examples for students about weight distribution and how engineers design bridges of different sizes and strengths. When using pieces of spaghetti to build the strongest bridge possible, a number of different tactics and strategies should be employed.

Using six pieces of spaghetti, make a three-dimensional triangle, connecting the corners with marshmallows. This will entail building three different triangles by embedding the points of these pieces of uncooked spaghetti into each of the four marshmallows on the corners. Make four of these three-dimensional triangles, using individual pieces of spaghetti and marshmallows.

Line two long pieces of spaghetti up beside each other on a flat surface. Place a line of glue along the crevice between them, effectively gluing them together. Place another piece of spaghetti on top of this line of glue. Allow it to dry, bonding three pieces of spaghetti together. Add more spaghetti pieces in exactly the same fashion, by pouring a thin line of glue in the crevice made between the pieces of spaghetti. Five to seven full-length pieces of spaghetti glued together should be ample. Make two of these long five-to-seven-piece spaghetti support poles.

Line two of the three-dimensional triangles beside each other on one side, two on another side. They should be as far apart as the spaghetti support rods you have just glued together. Now attach the support rods to the marshmallows on top of the triangles on the left and the triangles on the right. You will now have two triangles connected by these thick spaghetti support rods.

Decide how wide you want the spaghetti bridge to be. The narrower the walkway is, the stronger it will be when using spaghetti. Break a number of full pieces of spaghetti up into equal lengths using your fingers. Glue these pieces between the spaghetti support rods, creating a small walkway for the bridge.

#### Tip

The more pieces you glue between the support rods, the stronger the bridge itself will be, as it will be thicker. Consider using smaller marshmallows on the feet of the triangles and larger marshmallows on the top, so that there is more flex for the spaghetti bridge when weight is put on it.
