Experiment of the week: The nose knows noses

Messing with strangers when they don't realise it is most hilarious, try to contain your laughter as you make people do what you want without them knowing it.

WHERE: Public transport, board meeting, preferably where others are facing you.
WHEN: Whenever
WHO: Strangers and friends
WHY: For kicks

A most amusing trick while being bored to death on the train or in a PBL* is to scratch or rub your nose lightly and watch how many people do the same. It usually takes a maximum of three seconds for the people across from you and beside you to follow suit.
