A video featuring "Vomiting Larry"

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.


  1. Maybe the fact the video is slowed down makes it appear as there is more vomit than what I’d expect, but damn it looks like Larry is a competition eater.

    1. One thing I had to experience first-hand over the last few days:

      Half an orange and a single slice of toast are enough to generate about a pint of projectile vomit. 

      Even if you were forced to empty your stomach just a couple of hours earlier, and did not have a glass of water in between. This happens as your bowels draw fluids from your body to help in (in-)digestion. 

      Besides, lots of air can be part of the mix, making the situation even more explosive…

    1. The first blast comes faster than Larry can think. Instantly, two-thirds of his field of vision are filled with vomit.

      At the second blast Larry will bend down. That is no voluntary action.

      From blast three onwards, Larry is covered in cold sweat and has full-body goosebumps. He may now consciously reflect on his animal state.

      After blast four there’s nothing more to pump out, yet the spasm continues…
