Im trying to imagine the world where a human could expel a particulate at 30 meters a second.

Imagine being able to spit from one goal line to another. In 1 second.

Now, go outside and spit, see if you can spit 10 feet, and time how long it takes your spit to hit the ground.

I think it's different dynamics than trying to hock a lugi 30 meters. Think cough or sneeze.
