I'm planning on bringing a chocolate tempering machine. Basically it can melt up to a pound of chocolate and temper it so that it crystallizes back into a good bar of chocolate. You can also make chocolate bars pretty easy. Will bring some molds.
With some cookies, fruit or pound cake you have an extra caffiene vector too.
Now what else can one do with chocolate? Remember the South Park Song: Chocolate Salty Bawls?
Should be good for a picture and a post somewhere.
