How can this "Bloody Brain" cocktail be made without alcohol? I found this recipe for a Halloween cocktail known as a "Bloody brain", here's a link, and I was wondering how I would go about making a non-alcoholic version.

The recipe involves strings of Bailey's Irish Cream that do not mix properly and form tendrils that bunch together and look like a brain. I would like to know how to achieve the same effect with no alcohol.
Most of the things in this are very easy to substitute.

Roses lime juice is sweet and non-alcoholic (and can be found in most supermarkets). 

You can easily sub in heavy cream for Baileys: they don't taste the same, but chemically they react about the same. 

Grenadine is just a pomegranate juice simple syrup. No alcohol there at all.

The only question is what you want to sub for the strawberry vodka. Some kind of soda, most likely. It's a question of taste. It won't be easy to get something that is both fruity and clear, but you might try white cranberry juice, or white grape juice.
