As a person who has slid over a wall from the hot tub to the pool head-first, I can tell you the bottom of a 3’ (1m) pool comes up to meet your face much faster than you’d expect. I assume the fence is to encourage people not to do that.

Cool idea. I’ve never one to motion sickness, like never. But this got me, the swoopy turns just really turned my stomach.
