Soap water forms lather because soap molecules have two distinct ends - one end is attracted to water (hydrophilic) and the other end is attracted to oil and grease (hydrophobic). When soap is added to water, the hydrophobic ends attach to the oil and grease, while the hydrophilic ends face outwards towards the water. This arrangement allows the oil and grease to be surrounded by the soap molecules and lifted away from the surface, creating bubbles and foam known as lather. **

To lather with soap, wet your hands or the area you want to clean with water. Then, rub the soap between your hands or on the surface to create a lather. Continue to rub your hands or the surface together to spread the lather and work it into a foam. Finally, rinse off the lather with water to complete the cleaning process. **
