I think we will find that out as well! Maybe the height/speed as well (if 530 isn't 53mph). I am going to go out on a limb and say 6 inversions, with the 6th being an inverted tophat
As far as the water goes, I am not convinced there will be a pond etc, seems like it would have already been dug, unless they dig it around footers, no clue. They did keep a couple of pump houses??? I know those other pipes behind dodgems are a lot bigger diameter, they seem like they would be for sewage, but I dont have a clue.... I dont think the ride will be over any pool of water though, but I do hope I am wrong on this as that would be fantastic!
