Ok, as always I was listening to a disney podcast on my iPod and i found something interesting that you guys might like! It's called a Hot Jet! Have you ever heard of it? It's something like this. The oil that makes the rides work, the more it runs during the day, it becomes hotter, and there for then there's less friction, and less friction means that it goes a whole lot faster. So for instance if you ride Space Mountain right at park opening the trains are a slower then if you ride Space Mountain again right at park closing, the trains are faster because they've been running all day, there hotter, and there's less friction! I hope you like and I hope this works for all of you and also if you have heard this before or anything else about this just post! ;)

Tip!

If you want to ride any coaster ride at any Disney park slow, then ride them early.

If you want to ride any of the coaster rides at any Disney park really fast, then ride them late towards park closing! ;)

Whoah, sounds interesting.

For example: Haunted mansion runs at approx. 2 mph at opening, and 2.5 at closing! :P

I sorta see the science behind this, but I'm not sure how much of a difference that would actually make. I'll have to try it next time I go to Disneyland.

Yes, I've heard about this. But I've also heard that certain outside coasters, e.g. Big Thunder Mountain, go fastest at around noon, not because of the fridtion or anything, (well, maybe) but because the oil/grease on the tracks is thinnest at that point in the day.

For example: Haunted mansion runs at approx. 2 mph at opening, and 2.5 at closing!.

Well, as HM is motor driven and set to a certain speed, that wouldn't apply. Just the Coasters.

I guess the theory is sound. Not sure how much of a difference you will notice, though. The coasters are run by gravity. Heavy vehicles go faster. If a rocket (on Space, for example) is too heavy, it would go too fast, and thereby catch up to the rocket in front of it and create a intrusion warning. Likewise, if it's not heavy enough, they can "sandbag" it, artificially added weight to speed it up. It's all pretty well regulated.

Interesting idea, though.
