You might think that soap kills viruses, but soap actually works differently. There are special molecules in soap called amphiphiles. These molecules break the outer layer of the virus. Then, the whole virus breaks apart. The bubbles trap the virus’ parts, which wash away with water. For this to happen, you must rub your soapy hands together hard! Make sure you rub the front and back of your hands, fingers, and fingernails for 30 seconds. Then rinse well!
