Watch: Bill Nye explains the science behind wearing masks in new TikTok videos

'Everybody, this is a matter literally of life and death.'

Bill Nye has posted two new TikTok videos explaining the science behind different types of masks.

In the video, Nye tests a number of different types of covering, from a knit scarf to a double layer fabric face mask, showing their effectiveness. “Face masks…prevent particles from my respiratory system from getting into the air and getting into your respiratory system,” Nye explains.

“The reason we want you to wear a mask is to protect you, sure,” the famed TV personality exclaims. “But the main reason we want you to wear a mask is to protect me from you, and the particles from your respiratory system from getting into my respiratory system. Everybody, this is a matter literally of life and death.”
