??????????? If you put black pepper in water and add liquid soap all of the ppper will seperate. Why does this occur? does it have something to do withcharged ions?

actually no it has to do with surface tension. with the soap addition you get mycells starting to form which move the pepper around. it's how teachers visualize it for students

My theory is that the soap destroys the tensile strength of the water's surface. The pepper, which is riding on the surface of the water, gets pushed to the edges of the glass as it clings to the water's membrane. This would also explain why some of the pepper will also drop to the bottom of the water once the soap is added. The surface membrane has been compromised. Just a theory.

Maybe black pepper doesn't like soap.
