Yawn-o-metre test
Take this yawn-o-metre test and see how long you will last before yawning.
Everyone knows yawning is contagious, but can you catch one through a screen?
This week, AsapSCIENCE has tried to tackle the mystery of yawning.
After dropping a video on why we yawn, they set up a little competition.
All you have to do is watch the video below and see how long you can go without catching the yawn.
I set up a stop watch and under the pressure didn't yawn but as soon as I clicked away a big ol' yawn crept up and the pearly whites were shown.
How did you do?
