Yawning is contagious and that’s a fact.
YouTuber Roman Atwood wasn’t satisfied with just reading it as a fact however, he wanted to experiment with yawning.
Cue: this video (which WILL make you yawn).
Atwood went on a journey to prove that yawning is the world’s most contagious prank. He travelled the world, emitting giant yawns at every tourist spot to see what would happen.
You will probably need to yawn during this three-minute clip. If you don’t, you defy all science. Well done.
