Brain Play-Doh Mold

thingiverse

This is a great tool for teaching kids about their brain in a medical setting. If you want to highlight a certain area of the brain, place some of one color where you want it in the mold first, then add the other color. This mold is not perfect as the play doh will get into the contact joints and make it impossible to get it closed, so you have to try a few times to get it right. The larger mold takes almost 4 containers of play doh to make, and the 80% size takes almost 2 containers. You can use something reusable inside for displacement if you don't want to use as much play-doh.
