'When you're out in public, please wear a mask.'
On TikTok,"The Science Guy" broke down how masks work — and why they beat other face coverings like scarves.In two videos uploaded to TikTok mimicking the “Consider the Following” segment of his hit 1990s kids show “Bill Nye the Science Guy,” Nye demonstrated why masks are absolutely vital in the era of COVID-19.
“Why do people in the scientific community want you to wear a face mask when you’re out in public?” Nye asked in the first video, answering: “Face masks ... prevent particles from my respiratory system from getting into the air and then into your respiratory system. Blocking the movement of air is an old trick.”
Nye went on to hold a scarf, a homemade face mask and an N95 mask in front of his face as he attempted to blow out a candle. The N95 mask was the most effective at restricting airflow and the scarf the least. See that video below:
