1. The Russian Roulettocoaster, Upper Mongolia. A roller coaster similar in context to Urbonas’s Euthanasia Coaster, the Russian Roulettocoaster is designed to inflict prolonged, extreme g-forces on its passengers, such that around one in six of them will not survive the ride. The testing and calibration process landed the entire surviving concept, building and operational teams of the project in prison, so rides on the Russian Roulettocoaster these days are thankfully rare. A variant version in which the car is occasionally diverted onto a track that ends in mid-air was never built, although plans exist.  
2. The You Don’t Have To Be Mad To Work Here But It Helps Building, Chicago. An entire office building themed around fairground rides for the wackier kind of modern corporation. Meeting rooms can only be accessed by tube slide, the toilets are located in a giant ball pool, and top floor access is by giant see-saw, forcing employees to co-operate and co-ordinate their operations in order to get to meetings with the boss on time. In a cost-savvy move inspired by behavioural simulation and optimisation tools, employees are kept svelte and expenses reduced by the free office cafeteria being located on a rotating floor, inducing minor feelings of seasickness.  
3. The tea spa, Highgate. A spinning teacup ride containing actual tea. The premise of the tea spa is that sitting in a large cup of green tea will rejuvenate and revitalise your skin, encalm you in a carrying on sort of way, and also make your clothes a little bit fashionably brown. Additionally spinning the teacups causes mild dizziness, which is absolutely the kaleiest sort of legal high, and sometimes inspires fascinating insights into fluid dynamics. For an additional fee, it is possible to put a cat in the room, briefly, before it runs away.
4. The Himalayan waterslide, Nepal. The exact location of the Waterslide is a closely-kept secret. It appears to be a cave, but about thirty metres from the entrance reveals its true nature: an enormous, mile-long waterside-cum-tunnel dug into the Himalayan rock by a reclusive billionaire. Those who have the resources to find and use the waterslide (and the gumption, as it is also unlit along most of its length) will eventually plop out into a wide pool in an artificial cavern deep beneath Annapurna. Actually getting out again is another matter; the cavern contains the billionaire’s shuttered secret base, a number of nefarious evildoers thought lost to the world, a nuclear reactor best described as ‘cranky’ and the only remaining wild population of the Nepalese Burrowing Tiger. The cavern currently contains nearly the world’s entire supply of a certain type of adventure tourist (did you notice there were fewer of them about?). It is believed they may have formed a civilization, and many do not wish to return to the surface.
