My hypothesis is yes!
We tested with a candle at different distances
with and without masks
several different styles
We said the alphabet, spoke, and sang to see how the candle reacted.
We also tested with the mask over just the mouth and not the nose.
What did we learn?
Different sounds your mouth makes sense out different amounts of air. Singing sends out way more than just taking.
Every mask we tried worked better than no mask at all. And only wearing it over your mouth but not nose is just dumb.
So wear a mask to stay safe and to keep me safe! And maybe this sickness will go away soon!
