This is a new sport that looks like lots of fun! It's called Aqua Climb, and it is a combination of climbing and water sports combined. If you fall off, you land in the pool, not bad at all! In fact, I might like to try it and let go on purpose just to splash in the pool on a hot day.
It was designed by Christofer Born, a German industrial designer who combines structural work and art. Well done, Christofer, this looks like tons of fun!
