I'm doing an experiment where I bring a probe very close to a well full of fluid and then very slowly lower it to obtain some force deformation values. The material behaves very much like a fluid and when I bring the probe close to the fluid, it sort of jumps up and grabs the probe and forms like a "column?" that actually pulls on the probe rather than pushing on it.
Anyway, I'm trying to coat the probe with an oil or something that will prevent this, but I don't know how to look into it because I don't know what its called or how its described in the literature. Any ideas on what this phenomena is called?
