Bill Nye is bringing back his popular face mask TikTok PSAs once more, lest people need another reminder of their importance. On Dec. 5, the go-to Science Guy reiterated the necessity of masks to curb the spread of COVID-19. He showed a map of the United States where people are wearing masks compared to another map that shows the rise of the virus. "I don't know who needs to hear this but . . . masks work," he captioned the video. "Wear one."
Nye also took the opportunity to dispel a myth perpetuating about the effectiveness of masks. "There's a perception that a virus can travel through the fibres of a mask like this red dot," he said, using a colander and matchstick as an example. However, he explains that the virus can't travel by itself. Instead, it'll travel in droplets of spit or snot and get tangled in fibres, remaining trapped. "So please, everyone wear a mask," he concludes. Oh, and you can hear him just fine through it, too.
