Sneezes and Coughs Act Like ‘Mini Atomic Bombs’ and Regularly Exceed Two Meters

Remember, there is no hyperbole in science.

Always good for a Loughborough:

Researchers at Loughborough University have created a mathematical model which shows that droplets can reach more than 3.5 meters, without a facemask, significantly increasing the distance needed to stay safe.

Dr. Emiliano Renzi and student Adam Clarke have published the results in the journal Physics of Fluids.

Using data collected from experiments carried out in his bedroom

. . . Wait a second . . .

— due to the lockdown and closure of university labs —

(they hastened to add)

Dr. Renzi found that the largest droplets consistently traveled further than two meters.

It is due to a phenomenon known as a buoyant vortex—the turbulent motion of hot, dense air that we eject together with the droplets when we cough or sneeze.

…

Dr. Renzi said: “… In some cases, the droplets are propelled in excess of 3.5 meters by the buoyant vortex, which acts like a mini atomic bomb.”

Well, that settles it.

You are weapons of mask destruction. You’re all carrying Hero-shamer bombs. How dare you leave your house? How dare you?

Remember, there’s no hyperbole in science.

Researchers: COVID-19 Spreads Ten Meters or More by Breathing
Queensland University of Technology via Phys.org | July 6, 2020

A plea issued by 239 scientists from around the world to recognize and mitigate airborne transmission of COVID-19 addressed to international health authorities is to be published in the journal Clinical Infectious Diseases.

…

“At typical indoor air velocities, a 5-micron droplet will travel tens of meters, much greater than the scale of a typical room while settling from a height of 1.5m above the floor.”
