Watching A Sneeze In Slow Motion

If you are an allergic rhinitis sufferer, sneezing is probably a daily affair or seasonal affair. We don't really think much about sneezing do we? Have you for a moment, considered the science behind sneezing?

This is a video on sneezing. It is nothing gross. Believe me, in fact it looks rather beautiful! This video by Science Friday is shot with high speed capture of the mucus and gas from human sneezing. Using high speed camera and fluid mechanics, Dr. Lydia Bourouiba and Dr. John Bush of MIT Applied Mathematics study the role of gas clouds during sneezing. Cool!

P.S.: This is also a reminder why we should always cover our mouth and nose when we are sneezing.
