Water, oil and detergent

We combined oil and water and tried to mix it. The oil kept returning to the surface. We had many suggestions as to why this happened. We learnt that water is hydrophilic and oil is hydrophobic and moves away from water. We then added detergent and made an emulsion. Detergent is amphiphilic and is attracted to both water and oil. Kitchen chemistry is great fun!

It was amazing that the oil is lighter that water.
