Spaghetti bridge instructions

Updated February 21, 2017

Spaghetti bridges are often made in elementary science projects or for elementary school projects for various reasons. The basic spaghetti bridge shows elementary students the strength of different shapes by making a bridge from spaghetti and a bridge from rounded linguine and determining which can hold more weight. The basics of making a spaghetti bridge are very simple and require very few materials.

Make two triangles with the spaghetti. Connect the three sides of the triangle with three marshmallows at the corners. Stick the spaghetti into the marshmallows so that the triangle stays together.

Place three piece of spaghetti into the three marshmallows going upward and away from the triangle. Form a pyramid and bring the spaghetti together at the centre. Use a fourth marshmallow to keep the shape of the pyramid. Do the same with the second triangle so there are two pyramids.

Stick one raw spaghetti in the marshmallow at the top of one pyramid. Bring the second pyramid close enough to place the other side of the spaghetti piece into the second pyramid. Check that all of the spaghetti pieces are tightly pressed into the marshmallows so that it will not come out.
