Hydraulics

My friend John in England sent me this amazing video.  It's quite long (9:14) but after the video is set up you can fast forward to about 5 minutes to escape the German commentary, and you can easily see what the heck these guys are doing.  It gets pretty boring in Germany in the winter, and you have to invent things to do, but nonetheless, this is unbelievable.  And the local guy is standing underneath.  Quite a tribute to German engineering. http://www.youtube.com/watch_popup?v=RobaJKGMMiE
