The Perfect Yawn

Can you engineer a yawn to become perfectly contagious?

A number of studies found that a medley of ordinary yawns on video played to a classroom for five minutes would induce a responsive yawn in 55 percent of the audience. So that was his starting point: could he design a yawn powerful enough to move from a 55 percent response right up to Total Yawn-ness?

He tried.

Our story (just push on the icon up above and cover your mouth) describes what happened next.

Listen to the whole thing. And yes, studying the spread of yawning has a real practical application.
