Please, look at this question:
http://answers.yahoo.com/question/index?qid=20070928100815AA2qN2R
Now:
A sealed horizontal pipe on wheels, contants low-viscosity liquid and a a small bublle in the middle. Both liquid and the bubble are initially at rest with respect to the pipe.

The pipe rolls on wheels on level floor, and bounces off the wall. The spring attached to the end provides elastic bouncing.
What will happen to the bubble?

Relative to the pipe, the liquid to the left of the bubble moves against the leftward acceleration so the bubble moves left in the direction of the acceleration. If the viscosity is nonzero, the liquid and the bubble coast (asymptotically) to a stop after the spring loses contact with the wall and acceleration stops.

I agree. The bubble is just the void where there's no liquid. The liquid is what moves forward. Causing the bubble to appear to move backwards.

The bubble will always move in the direction opposite the acceleration vector.
