The DoSeum is a place where interactive fun and hands-on learning come together—a place where minds are always at play.  During your visit, our exhibits, programs, and classes will encourage young minds to explore the joy of learning through connections to STEM, the arts, and literacy, but curiosity and exploration don't have to end when you leave!

Explore our DIY Activities, Storytimes, and Questions from Kids that were created for you to DO at home and stay connected with your family while keeping minds at play in between your visits!

DIY Marshmallow and Toothpick Bridge

What is a bridge? Why are triangles the strongest shape? Why do so many bridges look alike? Explore these and other questions while working together to build your own bridge out of toothpicks and mini marshmallows! Challenge yourselves to make the tallest, longest, widest, or strongest bridge. Become an engineer and design your bridge before you start building it. Perform multiple tests and improve your design. Just be sure not to eat all of your marshmallows before you’re done!

What You’ll Need:
  • Stale Mini-Marshmallows (about 50 per bridge)
  • Round Toothpicks
  • Spaghetti-Style Pasta
  • Cardstock, Construction Paper, or Cardboard (the road for the bridge)
  • Paper or Journal, and Pencils
  • Testing Materials: Small Toy Car, Weights (e.g., coins, nuts, and washers, etc.), Towers (e.g., two stacks of books)
Building Tips and Tricks
  • As the caregiver, stay as hands-off as you can throughout the project. Let the children try, fail, and succeed on their own merit.
  • Refrain from offering your opinions on their bridge. Instead, ask children to make observations about their bridge and its performance.
  • Remind children that if they eat their marshmallows, they’ll have fewer materials for building. While it’s generally not recommended to eat while making, it may be a good idea to have something to snack on during this project, simply as a preventative measure.
