One of the messages we are hearing every day right now as we all navigate the COVID-19 ordeal is the simple reminder to Wash Your Hands. As children, we are all taught the importance of washing our hands until it becomes (or should become) a second nature activity - like buckling up your seatbelt when you get in a car, or putting on a helmet when you ride a bike (you do do all those things, right? RIGHT?).
But as you stand at your sink umpteen times a day during our current situation, singing the Happy Birthday song to yourself over and over, have you ever stopped to wonder how exactly soap works? Why soap? Why not just water?
