North Carolina State University has an eerie vomiting machine that was built by scientists to study how pathogens spread between humans. 20 million Americans each year suffer from norovirus, a nasty stomach bug that causes inflammation and leads to pain, diarrhea, vomiting and occasionally even death.
This vomiting machine replicates the body parts that play a crucial role to the process of barfing -- the stomach, esophagus and mouth. The system uses tubes, a pressure chamber and a discomfort-laden clay face sealed inside a plexiglass box. The machine allows the researchers to control the pressure, volume and angle of the vomit.
While gross-looking, this vomiting machine will undoubtedly play a role in helping scientists better understand how exactly norovirus causes human suffering so that they can figure out ways to alleviate it.
