This is just a quick WIP from lunchtime (okay, slightly extended lunch ;)). The bottle is just a vertex cylinder, squeezed in the right places and thickness added. Inside is an ocean primitive, converted to vertex and scaled down. I used boolean operators to fit it into the bottle. The base is just a box model. There is no stopper on the bottle. I think you may see where this is going...

Only default glass/wood/water shaders at the mo.
