Having just spent a day at Knott’s Berry Farm, I’ve begun to notice that there are a few immutable laws that apparently apply to all amusement parks, as faithfully as Newton’s laws of physics.
[li]If there is a body of water somewhere, people will throw coins into it, even if there is no implication that the water has any sort of wish-granting or other powers.[/li][li]If there is a ride that allows you to dangle your feet, your feet will begin to dangle involuntarily.[/li][li]People are stupid, so there will be lots of signs for their benefit. (This actually has nothing to do with the amusement parks, but the parks make it more obvious.)[/li][li]Old rides which are too popular to replace will instead be repainted in colors which the park designers apparently think are hip and futuristic, but which are actually ugly as sin, thus crushing your childhood memories of the ride. (Cite.)[/li][li]The safety bars on rides are always more secure than they really need to be. [/li][/ul]
The most typical example of this last one is the lap-bar / seat-belt combination, where the seat-belt is only effective if the lap-bar fails. Which it won’t, because it’s been checked by the computer system, and at least one employee. This is of course because the laws governing their design are federal codes, not the laws of physics.
