## How do you do the marshmallow and spaghetti challenge?

The CHALLENGE: Build the tallest free-standing structure in just 18 minutes using no more than 20 sticks of spaghetti, one yard of tape, one yard of string, and one marshmallow. The marshmallow must be on top and cannot be deformed to hold it in place.

## How do you make a strong spaghetti bridge?

The method we used seems to work quite well:

- Draw the design on paper. We found the best way was to make a ‘net’ of the bridge.
- Cut out your design.
- Stick the spaghetti on.
- Add trusses to make your bridge stronger – these are the diagonal beams.
- Join the sides together with cross-beams.

**How do you build a marshmallow bridge?**

Steps:

- Place two marshmallows with the bases flat on your work surface.
- Insert a toothpick into one of the base marshmallows of the first triangle at a 45-degree angle and another toothpick into the side of the top marshmallow.
- Repeat the triangle making process from step 1 to create another matching trapezoidal shape.

**What is the purpose of a spaghetti bridge?**

A spaghetti bridge is a bridge (architectural model) made of uncooked spaghetti or other hard, dry, straight noodles. Bridges are constructed for both educational experiments and competitions. The aim is usually to construct a bridge with a specific quantity of materials over a specific span, that can sustain a load.

### How do you make a marshmallow spaghetti tower?

Steps

- Push 2 strands of dry spaghetti into 1 marshmallow.
- Make a right angle with 2 more strands of spaghetti.
- Add a marshmallow to each end of the spaghetti strands.
- Push 2 strands of spaghetti into each new marshmallow.
- Use 1 more marshmallow to connect the final ends of the spaghetti strands.

### How do you test spaghetti bridges?

Place a tub or spread-out newspapers under the bridge to catch falling debris and make clean-up easier. Put the strip of metal on the bridge (as the road). Then apply weights on the chain, starting with 5 pounds and working up to 50 pounds, or until the bridge breaks. Allow students time to re-design and re-test.

**What is the Spaghetti tower marshmallow challenge for kids?**

This Spaghetti Tower Marshmallow Challenge is definitely the best way to keep small kids interested and attentive. It will also help them in boosting their fundamental thinking and creativity skills as well, regarding shapes and designs. In a world dominated by technology, this is indeed a welcoming change.

**How long does it take to build a spaghetti and marshmallow tower?**

The challenge is simple, just build the tallest free-standing structure possible (oh, the marshmallow must be on top!). You have 18 minutes. What makes this interesting is that Tom Wujec has run dozens of these spaghetti and marshmallow tower challenges across the world, with a variety of different participants.

#### How did Mary use marshmallows as a support for the Spaghetti?

By experimenting and looking at the example one in front of her she realized she needed to use marshmallows as a support to put more than one spaghetti piece into it. By putting them in at different sides she saw that she could start to build a more stable and exciting structure.

#### What is the design process for the Marshmallow Challenge?

The team will practice the design process that includes thinking, doing, prototyping, and iteration. This last point, iteration, may be the most important. Watch the video at the end of this post for more on that. Oh, and what group historically performs the BEST in the marshmallow challenge?
