When you sneeze, how fast do particles fly out of your mouth and nose?
Can you believe 100 mph? If your sneeze was a car, you'd get a ticket for speeding! A sneeze is your body's way of getting something irritating out of your nose. Your nose feels a tickle and the sneeze center in your brain responds by coordinating muscles in your belly, chest, and diaphragm to ah-ah-ah-choo! And out flies whatever was annoying your nose.
