How would you react if you found five total strangers staring at you in the street?

That was the question this group of Lebanon-based pranksters and YouTubers (HowAboutBeirut) attempted to answer with this 'social experiment' video.

The result is more tense than funny as the five performers (three girls and two guys) approach members of the public at random on the street in Beirut.

Reactions range from genuinely freaked out to downright perplexed.
