Interesting roller coaster ride...

That was fun, though I kept hearing myself say "That won't work like that". I was undecided as to whether it was a hoax right up till the "catapult" thing that shot the carriages up into the air on random tracks. Then I was convinced it was a hoax. And sure enough, the credits verified that it is.

Still, a fun, engaging video.

that last one looked like fun

Cool CGI. Not sure I'd want to go on any of those rides.
