First, that the oil is less dense than water, second, that oil is not soluble in water.
The property of water that allows things to float is buoyancy. Water exerts an upward force on objects placed in it, which counteracts the force of gravity pulling the objects down. This buoyant force is what allows objects to float in water.
Objects that have a density similar to water will float in the exact middle of the water. This can include various types of wood, some types of plastic, and certain types of foam.
Some plastics will float in water and others will sink. It depends on the type of plastic and in particular it depends on the density of the plastic material. This property is used as a method for separating the different plastics sent for recycling. Polyethylene and Polypropylene, for example, will float in water while PVC and ABS will sink.
The property of ice that allows it to float in water is the ice's low density. When water freezes into ice, the molecules arrange themselves in a way that makes the ice less dense than the liquid water, causing it to float.
The property of water that causes ice to float is its density. When water freezes into ice, the molecules form a crystal structure that spaces them apart slightly, making ice less dense than liquid water. This lower density causes ice to float on the surface of water.

Buoyancy; negative density.
The types of objects that will float on water are foil, most rubber, and some plastic.
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.
Some plants, like water hyacinth, float in water. They have special types of leaves that help them to stay afloat.
Surface tension of water is the property that allows a needle to float on water. This is due to the cohesive forces between water molecules at the surface, creating an invisible film strong enough to support the needle's weight without breaking.
