DSDN 112 - Ideas for presentation

I've bought a massive cup for my center piece of my presentation and also some glass to surround it. With the big cup I'm thinking of putting thick red icing that drips from the top and then sprinkle white icing sugar on top of the icing or maybe not. My goal is to make the appearance of the drink to look disgusting along with the presentation as well but then when you actually try the drink you are amazed at how good it is!
