# Movement through vibration

I have a circular container with a flange which sits inside a hole in a table which is mounted on vibration mounts and is vibrated by a linear vibrator. The container is a clearance fit in the hole, but is retained by two large O-rings which give a friction fit. When I apply the vibration I notice that the container is rotating anti-clockwise & rising out of the recess. Is this purely a function of the vibration and can it be applied in a way reverse this reaction?

There is only one extrinsic thing on Earth that causes things to happen with a particular handedness and it is very unlikely to apply here: there exists a very weak force called the Coriolis effect, which makes anything that rises upward drift slightly to the West, and when something falls then it drifts slightly east. In addition motion towards the nearest pole (as in North or South) acts like "falling" and motion towards the equator acts like "rising" for these purposes, because it's distance-from-the-rotation-axis, not distance-from-the-center, which matters here. So that could hypothetically cause such an asymmetry, but the effect is very weak because the Earth turns so slowly: the $F/m$ of the force is the characteristic speed $s$ that the thing vibrates at, multiplied by $2\pi/\text{day}.$ So if the linear vibrator moves back and forth by 1 mm, then even if it vibrates at a frequency of 100 kHz you would only see accelerations in the $0.001\text{ g}$ range, at most.
