WASHINGTON (SBG) - Bill Nye 'the Science Guy' took to TikTok on Thursday to demonstrate the importance of wearing a mask.

To demonstrate how face coverings keep particles from entering the air, Nye blows through several different materials toward a lit candle. The candle stays lit through each mask demonstration but goes out when he blows through a mere winter scarf.

"So the reason we want you to wear a mask is to protect you, sure, but the main reason we want you to wear a mask is to protect me from you and the particulars from your respiratory system from getting into my respiratory system," Nye says in the TikTok video.

The N95 mask appears to be the most effective in Nye's demonstration.

"Everybody, this is a matter literally of life and death," Nye adds. "And when I use the word literally, I mean literally a matter of life and death. So when you're out in public, please wear a mask."
