Q&A for How to Build a Spaghetti Bridge

Although some tapes may be stronger, glue is usually your best option. Not only is it often stronger, glue is easier to work with and fills in all of the gaps between the spaghetti to create a sturdier bridge.

It's harder to work with tape. It's also really easy to break the spaghetti while you're trying to tape it. Also, tape doesn't fill in the gaps between your pieces of pasta very well, so your bridge won't be as strong.

You could use a triangular-shape, as it is the most effective. Truss bridges can hold the most weight.

It depends on the bridge. I've seen bridges hold three kilograms, and another struggle to hold five hundred grams. If you follow this method, your bridge should be able to hold at least a kilogram if you do it right.

Hot glue is effective, because it sets just like epoxy.

Some Spaghetti Bridge competitions require specific pasta types and/or limit the glues that can be used. Keep in mind that the thicker the pasta, the more weight it holds. Choose a quick-drying, non-water-based epoxy.

Tape, glue, or anything lightweight and sticky.

Visit the JHU truss simulator website. It's free and it measures your tensile and compressive strength.

It is a truss bridge.

You could potentially use the spaghetti and stick it into the marshmallow, then position it to the angle needed. It'll take some work, but it could potentially function as intended.

Three 8 strands will work best with your situation. However, the optimal choice may vary with the type of pasta used. Do some experimenting––pasta isn't that pricey.

The tape, as there's no need to wait for it to dry and it doesn't need to be stored in a bottle.
