Ice bucket challenge by the GB Crew

  Updated   1 min read

Hi GoodBarbers, 
 
Our nomination for the #Icebucketchallenge is for all of you!
We had a lot of fun organizing and shooting the video and cleaning everything after this cold shower :)
 
But behind all this fun, there is an important cause: the ALS foundation has launched this viral challenge to collect money for research against ALS .

We wish you a very nice weekend!
 
Bye bye
