I know a idea chocolate cake.To make it you have to put chocolate on cake and it turns into chocolate cake. the chocolate cake can be flammable and can be eaten (heal more then chocolate). And another one is chocolate cream which is chocolate with cream and when it touchs chocolate cake it can be turn in to a solid which is a harden one.and knife that can cut cheese and blue cheese which you can make too and when cuted the blue cheese it release a gas that can hurt cook. I don't know how to call it short but you can called them short.
