Here is my 2013 Mad Scientist Fair entry. I asked my lab assistant for ideas and he thought it would be neat if we could remove someone's brain but keep it alive. I thought that was a great idea so, everyone, please meet my assistant.











I used a Jell-O mold and rubber compound to make the brain. The tongue (which moves and curls) I made from sculpey, then made a Dragonskin mold of the model. I cut some plastic ribs from a 1/8" plexiglass sheet, ran some bead-stringing wire through the ribs (anchored to the last rib), spaced them in the Dragonskin mold and poured in the rubber compound. This is the same approach as making moving tentacles. Anyway, the eyes are hand-made from acrylic using Dragonskin molds and photoshop irises. The ears and cochlea are sculpy and wire. Then there are a bunch of wires and push rods. I turned the sheet cake pan upside down and used it as a base for my rods and stuff. This pan fit inside the larger roast pan and was covered by the bloody red beat juice.

Here is a video:

Damn, this is impressive even without the items you couldn't include. He is totally ready to star in a scifi or horror movie.

LOL @ "all organic":D

I normally don't go gory for Halloween, but with a few tweaks, he could go kid friendly.
Just add marshmallows to the beet juice in the pan:D

That's kind of disturbing. So that must mean you did a wonderful job! :) The tongue movement really gets me.

Awesome and very well done, GOT!
The tongue, brain, blood, eyes and the metal parts are all stunning details.
After all that work you ran out of the pennies to animate it for the contest entry...DAMN!
Amazing static prop though.

I hope you show us the running prop after the contest.
Good luck!
