Why do the gold flakes in Smirnoff Gold neither float nor sink, but instead remain suspended in the liquid? Even if you move the bottle, they don't really move.

The special thing about gold foil is that it can be made to be amazingly thin- sometimes descriptors like 1 atom thick get thrown around. That means the gold foil essentially has no weight. While gold is denser than lead and would sink very easily, with gold foil the resistance from the water dwarfs the force of gravity on the gold causing it to sink so slowly that it appears to be suspended.

An analog might be tissue paper in air- if you have a big block of tissue paper, it falls very quickly, but a single piece falls slowly. It's the same effect except the water has much stronger resistance than air. 

If you wait long enough without disturbing the bottle, the foil would settle on the bottom.
