Why Masks Work: A Slow Motion Demonstration (Plus a Guest Appearance by Dr. Fauci)

The Slo Mo Guys spe­cial­ize in tak­ing every­day occur­rences and slow­ing them down … way down, so that we can see them in a new way. In this clip, they let you see what hap­pens when you talk with­out a mask, and then with a mask–all in order to demon­strate why a mask helps pre­vent the trans­mis­sion of COVID-19, a dis­ease that’s main­ly spread when peo­ple are exposed to res­pi­ra­to­ry droplets car­ry­ing infec­tious virus. Around the 4 minute mark, the host is joined by Dr. Antho­ny Fau­ci, who offers com­men­tary on the footage.
