Why Are These Two Scientists Sneezing On A Rabbit?
Mechanical sneezer, 1940 Popular Science archives A bizarre scene from the Popular Science archives Let's take a break from trying to wrap our brains around quantum teleportation and robot aliens, and focus on some simpler science: How do sneezes work? That's the mystery two researchers are working on in this photo from the April 1940 issue of Popular Science: Infectious germs are spouted from the mouth of a mechanical sneezer developed for medical research by William F. Wells of the University of Pennsylvania medical school in Philadelphia. By means of compressed air, the apparatus blows air-borne germs through a tube into a glass bell housing an experimental rabbit, to simulate the common method of transmission of germs by human sneezers and coughers. Hey, it only took us 73 more years to invent a barfing machine! Now that's progress.
