Will vinegar rise or sink when you add olive oil?

When you add vinegar to olive oil, the vinegar will sink. This is because vinegar is denser than olive oil. The density of vinegar is typically around 1.006 g/mL, while the density of olive oil is around 0.910 g/mL. Therefore, since vinegar is the denser liquid, it will occupy the bottom of the container when mixed with olive oil.
