This was a most interesting contraption -- a three-car (vertically) mine elevator that shot up 135 meters at the speed of light (it felt like, anyway). I was a bit nervous about taking it as I had heard of people screaming on it because it was so fast (!), but no way was I going to walk back up the 810 steps we had descended to the third level of the mine. It wasn't bad at all and was actually sort of fun. I thought the control panel on the right was fascinating, as well as the bells that ring every time the elevator is leaving or departing.
