HOWTO make a gory, exposed brain cap

Hallowe'en has come and gone, but it's always the right time for hats that make you look like your skull has been removed, exposing your brain!

It's best to study pictures of the human brain before tackling this project in order to best mimic the brain's convolution patterns when caulking the cap.

Weighing a little less than a pound and a half, this costume is still lighter than most professional bicycle and motorcycle helmets. Use a cap without an adjuster to ensure a perfect fit.

Project: Gory Brain Cap


  1. By the way, a propos of gory, exposed brain caps, real-time updating on comments is off, and it used to be on.  Did I do that, or was that you, or was it Disqus?

    1. Ha. I thought it was just me and I couldn’t figure out how to turn it back on. I’ll go look in the panel.

      Well… According to Disqus, it doesn’t work if comments are sorted by Oldest First. But that’s always been our default, and it worked up until a few weeks ago.

  2. I made this as my Halloween costume. It was really fun and pretty easy. I’ll be adding my notes and images to the Make: Project at some point soon. Mine was a bloodier brain.

  3. Freshly opened = pink.
    Stale = Grey.

    So, imagine he just popped his skullcap for an inspection.
    (Hey, add a squashed cranium-residing parasitic twin for extra gore.)
