The best you can hope to achieve with a mask, is that the direction of airflow of air exhaled is diffused. When you talk, the air exhaled from your lungs will hit the face mask, and be re-directed and "filtered", and the velocity of exhaled air will decrease in a straight line out the mouth.
So you can hope for a reduction in droplets going out in a straight line, and not much more.
That is about it!

A simple experiment will provide ample clarification. Get a smoker to exhale smoke through a mask. Even if you know of no smokers, I think you can visualize the result.
Expecting the smoke to be contained is not the right answer.
As with so many other things, the Marxists have taken the wearing of masks as a visual clue to your submission. It has become a Star of David, that shows the rulers who are meek and who are not. Science plays no role in it, the rulers want compliance! And even better, policing by the useful idiots. So the do gooders can start bashing people up.
Worked in the original Cultural Revolution, will also work here.
That is why it is mandatory to wear face masks in ZOOM/Skype meetings:

If anybody is left, with any brains remaining, this must surely be classified as "
Stupid" but a very good indicator of what we are dealing with!
Face it, (pun intended) this is our own version of the cultural revolution. People should go and read a bit about it. It will give you a good road map of what lies ahead. We are ruled by dyed in the wool Marxists, aptly supported by useful idiots in the most unexpected places.

Make no mistake. They are after you in every imaginary way. They will try and control you and everything you do! And when I say anything, I mean ANYTHING! They have only just got started. Don't expect anything to make sense anymore. The only goals are power and control.
As a Swiss saying goes, "your neighbour is the best policeman."
The world has gone mad.
No doubt about it.
