Marshmallow Challenge

🍝 The Marshmallow Tower Challenge

🎯 Build the tallest freestanding structure—with a marshmallow on top!


🧠 What Is This Challenge All About?

You and your team will have 18 minutes to build the tallest freestanding structure possible using spaghetti, tape, and string…
But here’s the twist: The marshmallow must go on top—and stay there! 🏗️


🧰 What You Get (per team):

  • 20 sticks of uncooked spaghetti 🍝

  • 1 yard of masking tape 🎗️

  • 1 yard of string 🧵

  • 1 standard marshmallow 🍡

  • 1 pair of scissors ✂️ (optional)

That’s it. Use your materials wisely!


🔧 The Rules:

  1. You have 18 minutes to build. ⏱️

  2. Your structure must be freestanding (no leaning on walls, books, or people). 🏛️

  3. The entire marshmallow must sit on top—don’t squish it!

  4. You can break or cut the spaghetti, tape, or string any way you like.

  5. At the buzzer, the tallest structure that can stand on its own wins! 🏆


💡 Tips Before You Build:

  • Test your ideas early! Don’t wait until the last second to add the marshmallow.

  • Think about triangles and strong bases for support.

  • Communicate with your team—divide roles and sketch a quick plan.

  • Keep it simple. Fancy isn’t always stable! 😉
