  1. 1

    Cut a block of styrofoam evenly in half (if you want to cut out the shape of the brain looking from the top down, you can do that first).

  2. 2

    Delineate the different sections of the brain using coloured markers. Draw carefully as these will be your guidelines for cutting into the styrofoam.

  3. 3

    Cut along the marker lines to show the contours of the brain.

  4. 4

    Finish with fine grit sandpaper and seal with acrylic paint if desired.

  5. 5

    Indicate various parts of the brain using tabs on stickpins or paint the sections accordingly; e.g., frontal lobe, cerebellum. Utilise diagrams from a book or the Internet for reference.

Tips and warnings

  • A dull tip serrated knife works best and is the safest when carving into the styrofoam. As always, handle any knife properly and safely.
