It's meant to resemble strip mining equipment, more particularly the
hydraulic nozzles and it shoots water towards the helix. It does not get you wet, the train misses the "line of fire".....errr...make that "line of water"; all the times I rode Saturday I barely noticed it while actually on the ride. While I think it is a really cool theming touch, I think somewhere near the ride they need to put a sign explaining what the purpose of such a water cannon in strip mining is, with a picture, so people will know what it's supposed to represent.
