By popular demand (and the help of intrepid readers Broan and theophrastvs), I present you a video clip of the humanoid robot known as Vomiting Larry.
Larry is used to study the way particles of puke become aerosolized, and how those particles spread and help infect other people. That's important, because it explains one of the ways that viruses spread by vomiting manage to end up in everyday things like, say, frozen raspberries. Aerosolized vomit isn't something you can spot. It doesn't clean up easily. And even just a drop of it can pass on plenty of viruses.
Carl Zimmer had a great piece up yesterday on norovirus, the virus that researchers are studying with the help of Vomiting Larry. His story has more info on how that virus spreads and will give you a better idea of why Vomiting Larry is so important.
