Spaghetti and marshmallow challenge

A challenge that appears simple on the surface, which involves food and is great for teambuilding? Sign us up for that!

The spaghetti and marshmallow challenge uses common items for an experiment in creativity and communication.

Whether used for a team offsite, workshop warm-up, or an onboarding icebreaker, this game reveals how your group thinks, collaborates, and adapts under pressure, one spaghetti strand at a time.

What you’ll need:

The setup for this activity is simple. You won’t need a full-on kitchen, but you will need some level tables. Each team should have:

• 20 sticks of uncooked spaghetti
• 1 yard (or meter) of masking tape
• 1 yard (or meter) of string
• 1 marshmallow (full-sized, not mini!)
• Scissors
• Measuring tape or ruler
• An adjustable timer on display

‍

Divide participants into teams of 4–5 people and give each group the same set of supplies. Clear a flat workspace for each team, as the towers must end up freestanding (no walls, chairs, or extra support) and hold the marshmallow at its peak for at least five seconds.

Before starting, check that every team understands that the materials are limited. Once the spaghetti breaks or the tape runs out, that’s it (sorry, no refunds or exchanges!).

How to play (step-by-step instructions)

Here’s a step-by-step breakdown of how to start this teambuilding challenge:

Step 1: Brief your teams

Invite your teams into the construction site (aka the office or cafeteria) and explain the challenge clearly. Their task is to build the tallest freestanding tower possible that can hold a marshmallow on top. They’ll also be working against the clock, and the amount of time is up to you. We find that 18 minutes works best, as 15 feels too short, and 20 is a bit too long. In those 18 minutes, teams need to plan, build and test their structure. The marshmallow must be placed at the top of the tower and remain intact at the end of the countdown.

Step 2: Give out your materials

Hand out the same materials to every team (no favoritism and no extras) once they start. Encourage groups to check their supplies carefully and to delegate their roles in the group. They might get the best results if one person cuts, tapes, or tests. The key to this is collaboration right from the start, so make sure each person has a role before the building begins.

Step 3: Start the clock

Give them the countdown, then let’s get to building! The moment the countdown begins, you’ll see some teams get stuck straight into building, while others will plan more carefully. Both are fascinating to watch. Remind everyone that the marshmallow is a bit heavier than it looks, so they might want to test their structure as they go, instead of going into panic mode at the final minute.

Step 4: Check stability

When time runs out, tell each team to keep their hands off, and have them all step back. Each tower must stand on its own for at least five seconds while supporting the marshmallow. Any tower that collapses or leans on outside support is disqualified (no exceptions!).

Step 5: Measure and celebrate your noodle champions

Use your measuring tape to see whose tower stands tallest. Take a moment to consider your chosen winner, and once you’ve decided, start saying what you like about the non-winning towers. Every team should get a little shoutout for their designs, even if they are super wonky! This is a light-hearted teambuilding challenge, so keep it light with cheers for losers and team photos. Those crooked towers are often the most memorable.

Facilitator tip:

Encourage participants to iterate quickly and test early. The most successful teams usually build, break, and rebuild rather than overanalyzing. As the facilitator, resist giving design advice, as the discovery process is where the real teamwork happens.

Debrief: What did teams learn?

The challenge is playful on the surface, but there’s a whole lot of teambuilding happening in a short amount of time. Watching towers rise and collapse in real time sets the gears in motion for communication and being able to adapt when faced with uncertainty.

• Prototype beats perfection: The most successful teams are the ones that try new ideas and test them early, not those who spend 15 minutes planning and 3 minutes building. Early prototypes bring flaws to the surface and teach teams that feedback and iteration matter more than rigid plans.

• Communication makes or breaks the build: With the clock ticking, good communication becomes a team’s strongest tool. Actively listening to each other and sharing decision-making can turn chaos into collaboration. Those who communicate most often have the greatest output.

• Leadership and flexibility: Strong leaders will emerge naturally, but the best leaders are able to delegate, encourage and adapt, without trying to control everything. Every failed tower is a reminder that shared ownership leads to better outcomes than one-person command.

• Embracing and iterating on failure: Try as we might to stop it, every first attempt is likely to tumble. That’s the whole point. Your teams will learn quickly that recovery and rebuilding are as valuable in games as they are in your office projects. 

FAQs

How long does the challenge take?

The session usually lasts around 25 to 30 minutes, including the setup, build and short debrief at the end. It’s perfect as a warm-up activity or energizer during a workshop or offsite.

Can the challenge be done virtually?

With the right preparation, yes, the challenge can be done remotely. Each member can build their own mini tower at home while joining a shared video call. Materials can be mailed in advance or substituted with what people have on hand.

‍What’s the ideal team size?

Generally, groups of four to five work best. Smaller teams communicate faster, while larger ones can quickly become tangled in too many ideas.
