Note to recorder:
Natural speed, please
A soap molecule is perfectly suited to mixing oil and water because it shares some qualities of each. The alkaline substance that helped create it gives it a polar “head” at one end. The electric charge at the head makes it “hydrophilic,” or water loving, since the hydrogen atoms in water molecules have slight positive charges. When you turn on the faucet, the head of the soap molecule will readily bond with the nearest water molecule.
