Researchers at the University of Colorado Boulder, wondered if they could use lasers to visualize this aerosol plume, and measure the speed and trajectory of the particles. They set up green laser beams over a commercial toilet without a lid, positioned two cameras a few feet away, dimmed the lights and flushed the toilet. The lasers illuminated the tiny particles ejected by the toilet, allowing the scientists eyes and the cameras to clearly see the resulting spray. The toilet they used in the study, was a brand new clean commercial toilet, filled only with tap water. Airborne particles ejected from the toilet traveled at speeds of up to 6.6 feet per second and reached 4.9 feet above the toilet, smaller particles measuring less than 5 microns, hung in the air for more than a minute. Aerosols can transmit infectious diseases including SARS-CoV-2, influenza , norovirus and other viruses, which have been shown to survive on the toilet bowl surface for several days.
