Many people experience norovirus as what's called projectile vomiting, which is literally

like across the room.

Epidemiological studies have suggested that such spirited spewing can aerosolize the virus, putting others at risk.

But Jacis says that mode of transmission's never been verified.

You know, in an ideal world, you would have somebody who had norovirus vomit,

and then you probably would collect the, you know, aerosols that came out of that vomiting event.

Sadly, or maybe thankfully, our world is not ideal.

So instead...

We decided to build a simulated vomiting device.

Yeah, you heard right.

A simulated vomiting device. The device mimics the upper

GI tract, an artificial stomach with a pressure pump and a ball valve sphincter muscle leading up to

the esophagus and throat. Vomit spews from a human-looking mask into a plexiglass box, where air
