I've found the perfect activity for our next Psych Club meeting: making Brain Cakes. This seems the ultimate way to combine two AWESOME passtimes, studying neuroscience and eating fattening confections. Though, if you check out these directions it seems we might not be able to finish this in one lunch period.
Up for something easier? How about creating a cortex from Jello using a Brain Jello Mold? Though given the disturbingly realistic result, it may be a better activity for your next game of Truth or Dare.
