    20 seconds

    The CDC recommends scrubbing for a full 20 seconds.

  2. What song does the CDC recommend humming TWICE while handwashing to properly measure time?

    "Happy Birthday"

    According to the CDC, humming the tune of "Happy Birthday" two times will get you to the recommended 20 seconds of handwashing.

  3. Is warm or cold water better for washing hands?

    Correct! 
    Wrong! 

    Either is fine!

    Warm or cold — they're equally effective, as long as you wash thoroughly!

  4. Which method of cleaning your hands gets rid of more germs?

    Correct! 
    Wrong! 

    Soap and water

    The CDC notes that washing your hands with soap and water is more effective because hand sanitizer does not get rid of all germs. Still, hand sanitizer can be a great backup if you don't have access to a sink with clean water.

    Correct! 
    Wrong! 

    You need to wash all of these!
