Another great idea!!!

Party, sorry!

Your were right, it's a human part for a party LOL

It's a table size prop - slightly smaller than lifesize if I recall. (Don't have one in front of me right now - mine's packed away.) Kind of cool but I wish I could find a way to get the worms to wiggle now and then

For a more rubbery jello brain, try mixing half blue jello and half vanilla pudding.  The pudding will make it more opaque and will stiffen it up quite a bit.  My sister did this by mistake when making jello shooters for a party; they came out like gummi bears - quite chewy. 

There is a white version of Great stuff.  I think it is latex based instead of polyurethane.  Or you could try colring some silicone caulk before adding it to a brain mold in layers.

Where do I get a brain mold???

I bought mine at one of the Halloween Stores last year.

I like this idea, I am doing an undead wedding theme,for my haunted living room and needed some weird food items as well,sure wish I was where my sister lives in Fl.,they sell chickens feet,it is supposed to be a delicace. I have a Billy Bones fish similar to The Billy Bass,but this one is Bones, I am going to jazz it up with some of The Rippers fake fishing worms.
  I like the playdough idea and I already have a brain mold. I think I will try it and paint it with flourescent paint and put a blck light over it. I also have a talking head in a candy dish,I am going to do something with  as well,perhaps,Potatoes,Carrots and Onions around it and sit it on a silver platter. Thanks for the great inspiration.
