MRI 3D cardboard modelling

Inspired by the layers recorded by an MRI scanner we are experimenting here with 2D layers of cardboard to create 3D shapes – why not have a go yourself!

You will need

  • old cardboard
  • scissors
  • blu tac
  • wooden skewer


  1. Cut out some increasing sized circles in cardboard and thread these onto your skewer leaving a gap. TIP: to make a globe shape cut 2 of each size and one large centre ring.
  2. Try out different shapes to see what effect you can create. We tried a stack of 3cm squares of cardboard and once threaded on your skewer gradually twist each one from bottom to top. This created a spiral sculpture.
