Why does food dye not mix with oil?
Vegetable oil is a non-polar molecule. These two substances do not mix together, they are imiscible (they will not mix together). Food coloring is a polar molecule so it WILL mix with the water. The water and the food coloring are both polar molecules and will mix together.
Does food coloring dissolve in oil?
Food coloring dissolves in water, but not in oil. So when you pour in your food coloring/oil mixture the oil will float at the top of the water because it is less dense, and the food coloring will begin to dissolve once they sink through the oil and into the water.

You might have seen this on streets after a heavy rain—some water puddles will have a coating of oil floating on them.
What happens when a glass of water is poured into a jar of vegetable oil?
The oil is LESS dense than the water. This is because the molecules of oil are larger than the molecules of water, so oil particles take up more space per unit area. As a result, the oil will rise to the top of the water.
Can you still recognized oil in water?
Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water’s hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.
What will happen if we pour some water and oil into a jar?
oil and water do not mix. The molecules of water can’t mix with the molecules of oil. Even if you try to shake up a bottle of half-oil and half-water, the oil just breaks up into smaller droplets, but it doesn’t truly mix with the water. Also, food coloring only mixes with water.
Is oil and water visible or settled down?
