Willy Wonka would be proud. 

In Bremerhaven, Germany there is a water slide that will have you travel through the vortex into a black hole filled with psychedelic colors and lights. The first time I saw this video, I immediately thought back to the original Willy Wonka movie, when the group travel in the boat through the tunnel. This waterslide, named "the blackhole," was updated in 2012 with the new colored lights and has been a hit with riders since. The slide is 25 feet tall and 256 feet long. Personally, I would love to see this slide even bigger. You could go through multiple different colored light variations and also through more twists and turns. Also, some sweet house music could be blaring through the slide as your going down. It would be like a dance party with water! Letting two people go down at once too would make it even more fun to enjoy. Hopefully we can see a slide like this somewhere in the United States.
