Some say that yawning is contagious, others say it's not. We had participants come in for what they thought was going to be a burger taste test. Unfortunately for them, it was actually a prank to see if they would yawn or not.
One of our participants was in every test. He was our false yawner. A yawn-stigator.
The first "real" participant fell victim to the planted yawn.
The second just seemed concerned for the yawner's energy levels.
Successful participant number three! Just like the rest of the real participants, she still thinks it hasn't even started yet.
One more yawn, please!
Four out of five participants yawned! Now there's just one thing left to do...inform the participants that there are, in fact, NO burgers...
Our final participant seemed pretty mad about the "no burger after being promised a burger" thing.
