optical illusions made it look like a ball rolled uphill and chairs could stand on edge
I went to one like this in Ohio in the 80’s as a kid. Balls rolled uphill, you could lean a ladder against a wall & climb it, when you went into the little house you walked leaning sideways…
I always thought it was a trick in how they built the place, but never figured it out.




That sounds right; I think it was next to Dinosaur Forest, with a bunch of statues and animatronics.
