Problem 12 - Marshmallow Tower

  • Pair children up or work with your child if they are younger
  • Give each team a bag of mini marshmallows (at least 50) and a bag of spaghetti
  • The task is to build the tallest tower possible in the time set (20—30 mins)


  1. The building materials cannot be eaten!
  2. The spaghetti can be made smaller.
  3. It must be a complete structure, i.e. everything attached.
  4. They can draw inspiration from anything they can see from their building area.
