UPDATE: I was wrong! (Can you imagine?)
Apparently there is an agency who supported Bruno Kammerl’s idea.. Thanks ‘ph’!

This is the proof that you don’t need a big agency to be creative and to attract some attention.
Bruno Kammerl, a German guy, has made a 35,2m long waterslide. His dream is to put this slide on a mountain as a big attraction.

He made this movie (real or not, I can’t tell) to attract sponsors to realize his dream..
Bruno, if your attraction is official, I will cross the world if needed to try it!
