This looks pretty awesome. Until I saw the target. Video looks pretty good though.
Direct link to the huge water slide launch.
It’s gotta be fake, a few feet short and you’d hit the platform. When I first saw it, I thought the pool was in a lake (so if you missed no big deal) but the wooden platform is just too much of a way to kill yourself if you missed (and it’s not a very big pool). So I vote “fake”…
