Recently we saw dozens or even hundreds of clips about a (welldiscussed) so called Icebucket Challenge.
The background: The challenge is a movement to promote awareness of the disease ALS. Once you get “nominated” you have to pour a bucket full of ice water on your head within 24 hours and nominate other persons. Can´t you fullfill your nomination you are called to donate some money to the ALS foundation.
The most interesting point of this challenge is its incredible viral success! I can´t even open my Facebook without seing new challenges anymore.
