Marshmallow Spaghetti Skyscraper (Engineering Relay): Rules, Setup & Visual Guide
Given only 20 strands of raw spaghetti and 1 marshmallow, teams have 10 minutes to build the tallest freestanding skyscraper that can support the marshmallow at the very peak!
🎯 Overview: Why Everyone Loves Marshmallow Spaghetti Skyscraper (Engineering Relay)
The Spaghetti Marshmallow Challenge is a world-renowned teamwork and design challenge created by Tom Wujec and played across schools, tech companies, and family gatherings worldwide. Teams of 3 to 5 players receive identical supplies: 20 strands of raw dry spaghetti, 1 yard of tape, 1 yard of string, and 1 standard marshmallow. When the timer starts, teams have 10 minutes to design and build the tallest freestanding tower that supports the marshmallow at the very apex for at least 15 seconds!
🛠️ Room Setup & Required Materials
Per team: 20 strands of dry spaghetti, 1 roll of masking tape, 1 meter of string, and 1 large marshmallow.
🖼️ 3-Step Visual Walkthrough
Follow these three visual diagrams to explain the game to your room in under 30 seconds:
Step 1: Equal Supplies Distributed
Each team gets 20 spaghetti strands, tape, and 1 marshmallow on their build table.
Step 2: 10-Minute Rapid Construction
Design stable triangular bases! Build upward while managing brittle spaghetti under tension!
Step 3: 15-Second Hands-Free Measurement!
Place the marshmallow on top! Hands off for 15 seconds—the tallest freestanding tower wins!
📋 Complete Step-by-Step Rules
- Divide players into teams of 2 to 5 members.
- Each team receives exactly: 20 dry spaghetti noodles, 1 meter of tape, 1 meter of string, and 1 marshmallow.
- Teams have exactly 10 minutes to construct their freestanding tower.
- The entire marshmallow must be placed at the very top of the structure; it cannot be eaten or cut into pieces.
- At the 10-minute mark, all hands must leave the tower. The structure must stand completely unsupported for 15 seconds.
- Measure the vertical height from the table surface to the top of the marshmallow with a tape measure or ruler.
🏆 Winning Condition & Scoring
The team with the tallest standing tower wins the Structural Architect Trophy!
🌶️ House-Rule Twist & Bonus Challenge
The 30-Second Earthquake Test: After measuring, the host gently bumps the table—any tower that survives the earthquake scores 3 bonus points!
💡 Host & Strategy Pro Tips
- Build with triangles! Triangular pyramids (tetrahedrons) distribute weight evenly, whereas squares collapse under pressure.
- Don't wait until the final 30 seconds to test placing the marshmallow—its weight often collapses top-heavy towers unexpectedly.
👨👩👧👦 How to Adapt Marshmallow Spaghetti Skyscraper (Engineering Relay) for Different Crowds
- For Kids & Family Game Nights: Play cooperative team rounds where parents and kids pair up together, and extend any 60-second timer to 90 seconds so younger players never feel rushed.
- For Shy Groups & Icebreakers: Start with two practice rounds where no points are tracked. Having the host go first breaks the ice immediately and sets a playful, zero-judgment tone.
- For Competitive House Parties: Use the House-Rule Twist above during the final tie-breaker round and award double points for creative answers!
