Hey there, curious minds! Welcome to Fizz Pop Wow, the super fun science podcast where we answer big questions with quick, exciting answers in less than five minutes. I'm Michelle, and today's question is squeaky clean. How does soap remove germs? Let's find out!
The Science of Soap and Germs
Have you ever wondered why washing your hands with soap is so important? What makes soap so special? Can we just rinse our hands with water and call it a day? Well, soap isn't just for bubbles—it’s a superhero against dirt and germs! But how does it work? It’s not magic—it’s science!
Why Do Germs Stick to Your Hands?
Germs like bacteria and viruses are super tiny. They’re so small that you need a microscope to see them. They can stick to your hands, doorknobs, and even your favorite toys. But why don’t germs just wash away with water? That’s because many germs are covered in a greasy, oily layer—kind of like butter on your fingers after eating popcorn. Water alone can’t grab onto grease very well. And that’s where soap comes in!
Soap to the Rescue!
Soap is like a magic bridge! It has two special sides. One side loves water—this is called hydrophilic. The other side doesn’t like water but loves grease and oil—this is called hydrophobic. When you rub your hands with soap and water, the soap grabs onto the greasy stuff, along with all the germs stuck inside. Then, when you rinse, the water washes everything away, leaving your hands fresh and clean!
