Its conceit—spinning teacups on a platter of concentric turntables—has given the name to an entire genre of carnival “teacup” rides, in which each cup serves a steaming serving of nausea. How much you’ll want to heave depends on whether you’re riding with someone who can turn the central wheel and get your twirl on within the 90 seconds allotted. The first time you ride, it’s emblematic, but for after that, it’s ignorable furniture, like a hall table you pass on your way to the rest of the house.
