Is six feet apart enough? | Chemistry And Physics

Life from six feet apart might not be far enough, reports a new study on the transport of fluids and particles in the journal Physics of Fluids, from AIP Publishing. The research says that fluids coming from our respiratory tracts when we cough, sneeze, speak or breathe travel through the air to unexpected distances even at light winds: a slight breeze of 4 kilometers per hour can transport saliva 18 feet in 5 seconds.
