“Why do people in the scientific community want to wear a face mask when you’re out in public?” Nye asks in his social video.
“Masks prevent particles from my respiratory system from entering your respiratory system … Blocking air movement is an old trick.”
Nye then uses a candle to show how much air and other respiratory particles escape from his mouth when covered with a variety of fabrics.
It starts with a simple simple handkerchief to show how it is used to prevent wind from its neck, but when it covers its mouth with it, the handkerchief is not as effective. The candle goes out.
He then uses a homemade two-layer cotton mask that has a cleaning tube on top to adjust it to his nose. The candle moves, but remains lit, indicating that even a DIY sewing design can prevent air and respiratory particles from escaping.
In a second video, he continues his experiment with an N-95 mask and the candle remains unaffected.
“The reason we want to wear a mask is to protect you, of course, but the main reason we want you to wear a mask is to protect us from you!” He shouts at the end of the video.
“It’s literally a matter of life and death.”
