Here are my supplies: 2 parts red playdough, 1 part blue (I would recommend making your own as well or buying a neutral colour and colouring it yourself, but this is all I could find at the dollar store), newspaper, duct tape, spray adhesive, corn syrup, food colouring and paint brush.
2. Wad newspaper into a ball and wrap it tightly with duct tape to make the shape you want. Roll pieces of playdough into long round lengths and spray the tape ball with adhesive before you start applying the pieces. I used a picture of a brain as inspiration for placement of my pieces.
3. Once your pieces are all on you can paint your brain however you want. I wanted to lighten the colour of mine so I used hair colour spray (halloween make up).
4. I then used corn syrup colour with food colouring to create the shiny bloody effect. I also used a bit of high-quality fake blood as well. I used the remaining corn syrup to create a pool of blood under my brain.
And voila! I was pretty happy with it and got lots of comments about my brain.
