REQUIRED MATERIAL:

S:Oil,Water,Pomegranate Sour,Cup

PROCEDURE :First we pour the water into a glass, then we pour the liquid oil. When we observed, the oil stood on the water. Later, when we put the pomegranate syrup in the glass, it collapsed at the bottom. Oil remained at the top, water in the middle, and oil at the lowest. The reason for this is the density of liquid substances. Liquids move according to density differences.
