In 1988, Shao-Chun Chu conceived a unique way to teach people about the human body — an amusement ride that would carry passengers through an enormous model of a sleeping man and woman:
An educational amusement apparatus forms a large building structure having an external appearance simulating a man and a woman resting partially under a blanket, wherein riders are taken through a succession of cavities that simulate internal organs of the man and woman. Entrance to a head chamber simulating an oral cavity is achieved by a stairway supported by a simulated arm of the man, the oral cavity having displays of teeth in normal and abnormal conditions, and serving as a staging area for a train to carry the riders. The train passes into a simulated cranial cavity of the woman, past a sectional display of simulated ear organs, and into a body portion of the building that is representative of the abdomen of both the man and the woman, first through a simulated esophagus, stomach, and intestine of an alimentary canal, through simulated urinary and reproductive tracts, then through a simulated liver and a simulated cardiovascular canal, and finally through a simulated lung and windpipe to an exit staging area of the building.
Chu hoped the ride would encourage people to take better care of their bodies and would be “effective in transporting a large ridership.” His 10-page patent abstract contains sentences that I’m pretty sure have never been written before (“Further, the structure continues to descend until the cars become partially submerged in the lake of the stomach, preferably with considerable splashing”). Unfortunately, to my knowledge it’s never been realized.
