We have known that soap is used to wash off oil and grease. It is able to do that thanks to the soap's structure of a non polar tail and a polar head. The tail is non polar and oil is non polar so the tail is able to interact with oil. The head is polar due to unequally distributed electrons, which has the ability to interact with water, which is also polar. Water and oil don't mix because water is polar while oil is non polar, "like dissolves like". Thanks to soap, the oil is formed spherically by the soap structures' tails. Their heads are connected with water so that water and oil are dissolved in a solution. By that, we are able to wash the oil off. In the video, after Meena ate the chocolate, she went to the bathroom to wash her hands with soap and get rid of the grease on her fingers.
