To figure out how best to prevent motion sickness, you first need to figure out how best to bring it on. Aerospace research has excelled at the latter, if not the former, and perhaps nowhere more triumphantly than at the U.S. Naval Aerospace Medical Institute in Pensacola, Florida: the birthplace of the human disorientation device. In a 1962 NASA-funded study, twenty cadets agreed to be harnessed to a chair mounted on its side on a horizontal pole. Thus affixed, the men were rotated, rotisserie style, at up to thirty revolutions per minute. As a reference point, a chicken on a motorized spit typically turns at five revolutions per minute. Only eight of the twenty made it to the end of the experiment.

Teaser Tuesdays is a fun weekly bookish meme, hosted by MizB of Should Be Reading. I change the rules a little bit to suit my own purposes: I hand pick the teaser, rather than choose one randomly. I also very frequently post more than two sentences. :)
