Spaghetti Tower Marshmallow Challenge

Spaghetti Marshmallow Challenge

Do you know about the Spaghetti Tower Marshmallow Challenge?

This is one of those legendary team-building challenges that I’ve been hearing about for ages and have never tried.

It encourages the design mindset and supports basic engineering principles. 

The basic idea is that a team is given a handful of supplies to work with — spaghetti, tape, and string — and given 18 minutes to build the tallest possible tower that can SUPPORT a marshmallow.

And the point of it? 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? The answer to that question is also in the video, and you will LOVE it.

Spaghetti Tower Supplies:

Each team gets the same set of supplies…

20 sticks of dry spaghetti

one yard of string

one yard of tape

one marshmallow

The objective

To build the tallest tower possible in 18 minutes that will support the marshmallow.

My two daughters, ages 4 and 6, and I set our timer for 18 minutes, and started to build. It was exciting, frustrating (spaghetti is nimble and brittle!), and fun. My little one lost interest quickly, but my older daughter stuck with it, pushing me with her novel ideas and keeping me going, right up until the timer ran out.

And, go!

Spaghetti Marshmallow STEM Challenge

We talked about how triangles build strong structures, so we started there. Our original idea was to build two structures – one that could support the other, to make our tower twice as tall.

As we got towards the end of our time, the bottom towner couldn’t support the weight of the second tower, so we chose just one of the towers to use as a support for the marshmallow. In the end, we measured our marshmallow’s height and it clocked in at 10.5 inches. Not earth-shattering, but at least we had a supporting structure!

I love my daughter’s idea to suspend the marshmallow from a string…

What we learned?

  • Triangles are good shapes for these structures
  • We probably should have built the second tower directly on the first one, rather than wait to add it at the end
  • We worked well together
  • Prototyping and iteration are important to the process
  • This challenge could lose a 4-year old’s attention 😉

What’s next?

I would love to try this out with our Girl Scout troop or with my older daughter’s friends. After watching Wujec’s video (above), I’m eager to see this in action with a group of young children.

    Whaaaaaat????? This is so cool. I am really excited to get my 17 year old sciencey step son in a room with my younger kids and have them do this as a bonding activity. (I’ll sit back and watch and eat marshmallows.)

    • Rachelle says

      Thank you, Jeanette! I bet that your kids would enjoy this, and it could be a good bonding moment. Enjoy your marshmallows :)

    These photos are so cool, is this your studio space? I am in love with everything here! Thanks for such a great idea :) xo bar

    • Rachelle says

      Thanks, Bar! It IS my studio. The kids love to spend time in there with me. Sometimes it goes haywire, but they usually like to busy themselves with some kind of project, which is win-win for everyone.

    • Rachelle says

      There are sooo many ideas out there, Allison! Isn’t it great? I’m happy to introduce you to it.
