Standard intro; this is a half-baked idea.
All space contains virtual particles. These virtual particles can exert measurable pressure (the Casimir effect).
Imagine a bed of nails. One side of the surface is flat, the other has many short, massive spikes coming out of it. Mass stretches spacetime. So, in a sense, there is more space on one side of the board than the other. (Tiny tiny yes I know.)
Assuming the 'density' of virtual particles per unit of volume is constant, there are more virtual particles on one side of the board than the other. This will create a pressure, pushing the board in the direction of the flat side.
In implementation, something like sandpaper would more likely be effective. But the bed of nails is a good image to start with; the main idea is that there is more mass on one side of the board; more spacetime curvature, therefore more space, therefore more virtual particles.
