Shit I feel it just on a trampoline.

If you produced force on the bottle as you dropped it so that the water inside is forced to the top because the bottle is traveling faster than the force of gravity, this would happen. If you just allowed gravity to take the bottle by just letting go, you wouldn't see the water go to the top until other forces took over forcing the bottle and water around. The water inside the bottle and the bottle itself would only have the force of gravity pulling it down and thus they both would fall at the same rate and the water would maintain it's location in the bottle.
