And of course, strawberry jello brains, courtesy of a dear friend who had these molds and was kind enough to share them.
We also played brain 'games' from this site http://faculty.washington.edu/chudler/experi.html
We learned what each lobe of the brain controls, as well as how each hemisphere controls the opposite side of the body.
(PS- my daughter declared this her 'Thinking Cap'. I found that highly amusing.)
