Do masks work? Think glitter and farts

Look, the whole mask debate is stupid.

Masks WORK, but they also DON’T. This is a virus in the air. If you’re wearing a mask, it prevents you from sneezing in someone’s face. They can’t sneeze in yours. That’s a great big reduction in viral load! Hooray!

Masks are one huge step in slowing down the spread of disease.

However, if you get into an elevator with three people who have Covid and you’re wearing a cloth mask, you’re probably going to get sick.
