Marshmallow structures have become a popular activity in engineering and architecture education, as well as in team-building exercises and competitions. The challenge is simple: build a structure using a set of materials, with a marshmallow on top, that can withstand a certain amount of weight or stress without collapsing. In this article, we will explore the basics of building a marshmallow structure, discuss the science behind it, and provide a step-by-step guide on how to make a successful one.
Understanding the Basics
Before we dive into the details of building a marshmallow structure, it’s essential to understand the basics of the challenge. The typical materials used for this activity include:
- 20-25 sticks of spaghetti or other brittle material
- 1 yard of tape (masking, duct, or packing)
- 1 yard of string or twine
- 1 marshmallow
The objective is to build a structure that can hold the marshmallow on top without collapsing, using only the provided materials. The structure should be able to withstand a certain amount of weight or stress, which can be measured using a weight or a timer.
The Science Behind Marshmallow Structures
Building a marshmallow structure is not just about creating a tower that can hold a marshmallow; it’s also about understanding the science behind it. The structure’s stability and strength depend on several factors, including:
- Center of Gravity: The center of gravity is the point where the weight of the structure is concentrated. A lower center of gravity makes the structure more stable.
- Balance and Symmetry: A symmetrical structure is more stable than an asymmetrical one. Balance is also crucial, as an unbalanced structure can easily tip over.
- Tension and Compression: Tension and compression are two fundamental forces that act on a structure. Tension occurs when a force is applied to stretch or pull the structure apart, while compression occurs when a force is applied to squeeze or compress the structure.
- Triangles and Geometry: Triangles are the strongest shape in engineering, as they distribute the weight evenly and provide excellent stability. Using triangles in your structure can make it more stable and robust.
Step-by-Step Guide to Building a Marshmallow Structure
Now that we have a basic understanding of the challenge and the science behind it, let’s move on to the step-by-step guide on how to build a successful marshmallow structure.
Step 1: Plan Your Structure
Before you start building, take some time to plan your structure. Consider the following factors:
- Height and Base: Decide on the height and base of your structure. A wider base provides more stability, while a taller structure can be more challenging to build.
- Shape and Geometry: Choose a shape that incorporates triangles and provides excellent stability. Consider using a square or rectangular base with triangular supports.
- Materials and Resources: Make sure you have all the necessary materials and resources before you start building.
Step 2: Create the Base
The base of your structure is the foundation of your entire build. To create a stable base:
- Use a Square or Rectangular Shape: A square or rectangular base provides more stability than a circular or triangular one.
- Use Multiple Sticks: Use multiple sticks to create a sturdy base. You can use 4-6 sticks, depending on the size of your structure.
- Secure the Sticks with Tape: Use tape to secure the sticks together, making sure they are tightly bound.
Step 3: Add Supports and Triangles
Once you have a stable base, it’s time to add supports and triangles to your structure. To do this:
- Use Triangles to Distribute Weight: Use triangles to distribute the weight of your structure evenly. You can create triangles using three sticks and some tape.
- Add Supports and Columns: Add supports and columns to your structure to provide additional stability. You can use sticks and tape to create these supports.
- Make Sure the Structure is Symmetrical: Make sure your structure is symmetrical and balanced. This will provide additional stability and prevent the structure from tipping over.
Step 4: Add the Marshmallow
Once you have a stable structure, it’s time to add the marshmallow. To do this:
- Use a Small Amount of Tape: Use a small amount of tape to secure the marshmallow to the top of your structure. Make sure the tape is not too tight, as this can cause the structure to collapse.
- Make Sure the Marshmallow is Centered: Make sure the marshmallow is centered and balanced on top of your structure. This will provide additional stability and prevent the structure from tipping over.
Tips and Tricks for Building a Successful Marshmallow Structure
Here are some additional tips and tricks to help you build a successful marshmallow structure:
- Use a Variety of Materials: Experiment with different materials, such as straws, craft sticks, or even newspaper, to create a unique and stable structure.

What is the objective of building a marshmallow structure, and how does it relate to engineering success?
The objective of building a marshmallow structure is to design and construct a freestanding structure using limited materials, typically straws, tape, and a marshmallow, that can hold the weight of the marshmallow without collapsing. This activity is often used in engineering and design education to teach students about the importance of teamwork, creativity, and problem-solving in the engineering design process. By building a marshmallow structure, students can develop essential skills such as critical thinking, communication, and collaboration, which are crucial for achieving engineering success.
The marshmallow structure activity also helps students understand the concept of constraints and how to work within them to achieve a desired outcome. In engineering, constraints can come in many forms, such as limited resources, budget constraints, or environmental factors. By learning to work within these constraints, students can develop innovative solutions that meet the requirements of the project while also being efficient and effective. This skill is essential for achieving engineering success, as it allows engineers to create solutions that are both functional and sustainable.
What materials are typically used to build a marshmallow structure, and why are they chosen?
The materials typically used to build a marshmallow structure include straws, tape, and a marshmallow. These materials are chosen because they are readily available, inexpensive, and easy to work with. Straws provide a lightweight yet rigid framework for the structure, while tape is used to hold the straws together and provide additional support. The marshmallow is used as the “load” that the structure must support, and its weight and size provide a challenge for the designers to overcome.
The choice of materials also reflects the constraints of the project, which is a key aspect of engineering design. By limiting the materials to straws, tape, and a marshmallow, students are forced to think creatively and come up with innovative solutions that meet the requirements of the project.
