Leave it to Casey Neistat to find a crazy water park (Tropical Islands Resort) in Germany while visiting with his son Owen. Well, technically he says in the video that it was Owen’s idea to visit this ex-military blimp hangar, but who cares? Casey films the entire experience much like he does everyday through his SnapChat Stories. Which if you already aren’t following him there, you totally should. Search: CaseyNeistat and for myself, JoesDaily. You won’t be disappointed.
