Oil floats on water because a drop of oil is lighter than a drop of water the same size. Another way of saying this is to say that water is denser than oil. Density is a measurement of how much a given volume of something weighs. Things that are less dense than water will float in water. Things that are more dense than water will sink.
Even though oil and water are both liquids, they are what chemists call immiscible liquids. That’s a fancy word that means they don’t mix.
