Spit...it's awesome. Now you can learn a ton more about it with Truth or Fail, the very simple YouTube gameshow in which I give you two facts
This is Hank Green for Truth or Fail. This episode was written by my man Adam Brown. Truth or Fail is a very simple YouTube game. All I'm going to do is give you two purported facts. One of them is true and one of them's not and you have to click on the true one or you fail. This week's episode of Truth or Fail is very near and dear to all of our hearts. Actually, to be perfectly honest, it's a lot nearer and dearer to all of our mouths. This episode is about spit. Spit, spittle, drool, saliva! So without further ado, I shall attempt to say it and not spray it in this edition of Truth or Fail.
Round number one.
Fact number one: The average human produces one gallon of saliva everyday. (Slurping noises)
OR
Fact number two: Saliva production drops to almost zero while a person is asleep.
