Ice cube attempt

So I've been trying to figure out how to photograph coke like they do for the adverts and such, with the bubbles and nice looking ice. I read somewhere that it's done using clear jello for ice cubes so I decided to give it a try.

My goal

You can't see anything but there is jello in there

After the jello set I cut it into cubes

And filled my pretty glass with some of my new ice cubes

Finally I set up my lights and began my first attempt at getting a great drink shot. The results are below, not too bad but not as good as I was hoping for.
