I guess I'm just having a hrad time seeing this as a chemistry experiment. To me it just looks like a plate full of goo....very grainy and out of focus. The grain looks intentional, but I am bothered by the poor focus.
A classic experiment - looks like balsamic or malt vinegar (which the USA sadly lacks any knowledge of). I think you should have added a human element too to make this much more dynamic. As it stands, it is rather passive.
