6 Fun Finds at Walt Disney World's Animal Kingdom

4. "Chemical" Pipes in the Dinosaur Queue

Whether you've ridden the Dinosaur ride once or a hundred times—those of you with dino-obsessed kiddos know what I'm talking about—there may be one funny little fact about the queue you haven't been aware of.

You know those red, yellow, and white pipes you see near the ceiling in the queue, just before boarding your Time Rover? The ones with chemical formulas written on their sides? Those formulas represent the primary ingredients of ketchup, mustard, and mayonnaise, respectively.

Weird, right? That is, unless you remember that McDonald's used to be the ride's sponsor.
