face mask experiment

Claim:

"A face mask protects others but not yourself."


Let's make  a simple experiment:


Hold a handkerchief (or a bandanna or a T-Shirt or ...) in front of your face.


Then breathe out.
The handkerchief will move away from your face.


Then breathe in.
The handkerchief will move near your face.


Conclusion:
While breathing in a higher percentage of air will be filtered.


Of course there are other aspects to be considered.


Now a little advice:
If your face mask has two gaps on both sides of the nose put some cotton wool in these gaps.
And:
WASH YOUR HANDS!
Finally a few videos about making your own face mask:
