Easy Brain in a Jar

Allen Hopps has a brain the size of a baked potato. Ok, now that I’ve got your attention I should probably rephrase that. Allen’s got a great tutorial on how to easily make a brain in a jar that starts out roughly the size of a baked potato and requires far fewer ingredients than I would put on said potato.

His method starts by balling up some aluminum foil and then adding some caulk to it to create the sulci and gyri (brain grooves). Once you drop it in a jar filled with water the size of the brain looks deceptively larger!

Items needed to complete this include:

  • 1 gallon jar
  • Aluminum foil
  • Gray silicone caulk
  • Black paint
  • White acrylic paint
  • Polyurethane spray sealant
