Can you explain the oil and water experiment and how it demonstrates the concept of immiscibility between oil and water?

The oil and water experiment demonstrates immiscibility, which means that oil and water do not mix together. When oil and water are combined in a container and shaken, they separate into distinct layers. This happens because oil molecules are nonpolar, while water molecules are polar. Since like molecules tend to stick together, the nonpolar oil molecules cluster together and repel the polar water molecules, causing the two substances to remain separate.
