Can a body sink in one fluid and float in another? give examples

Let us consider the condition of floating bodies: if the density of the liquid is greater than the density of the body, then it floats to its surface, respectively, if the density of the liquid is less, the body sinks, and if the density of the body is equal to the density of the liquid, the body floats in the thickness of the liquid. Based on this, we can conclude: one and the same body can drown in one liquid, and swim in another. For example, aluminum with a density of 2700 kg / m ^ 3 will sink in water (p = 1000 kg / ^ 3) and float in mercury (p = 13 600 kg / m ^ 3)
