Here's a couple of photos from a really cool club in Berlin which was set inside an old bathhouse. The dancefloor and DJ-set is down in an empty swimmingpool.
At one point during the night a big blow-up raft turned up and was thrown around the dancing crowd. All of a sudden the boat drops down and dissappears a moment and turns up again now with a really happy guy sitting in it. He "floats" around a bit on the crowd before falling abck down again.
