The NC State researchers spent two years building and then testing a miniature version of the upper digestive track—essentially a tube (esophagus) connected to a pressurized chamber (stomach). Then they mixed together fake saliva, fake vomit aka vanilla pudding, and a real virus. Norovirus itself is too dangerous to work with, so they used a bacteriophage harmless to humans called MS2. The machine heaved this mixture into a chamber, and a device vacuumed out any aerosolized particles for analysis. In a worst case scenario, a single puking episode aerosolized as many as 13,000 virus particles.
