Reading their article - cardboard box, video with an iPhone, etc. - I hope they didn't get a huge grant to do this - and ditto for getting a new one.
Ultimately, the conclusions from this group are if you block something it won't travel as far as if you don't block it.
SCARF SECTION:
Actually something worth considering:
Suppose you worry about coughs (significant from what I hear).
You consider coughs with no mask and with a mask. Now, the no-mask is basically obvious BUT what about the results of the with-mask . . . not in front of the mask, but to the sides . . . blowing sideways and even backwards into the surroundings. Or so one could hypothesized - based upon the type of mask and how well worn.
Interestingly, it may be that wrapping a scarf around your lower face would be more effective as it's far more omni-directional in its coverage. Several layers would obstruct droplet propagation and yet maintain decent air flow (breathing, pressure-surge venting).

I think the whole point was just to visualize the cloud of droplets leaving your mouth when speaking. There are many people around that doesn't think it happens.
About scarf vs surgical mask etc. The reason surgeons are using surgical masks is simply that they are sterile and disposable, which is important when you're operating someone. For stopping droplets I assume more or less any fine mesh cloth will do fine.

Until this article/video, I hadn't thought much of the scarf format - but then upon consideration of masks - to a great extent they'll share their effect between mitigation and redirection.
Interestingly - "fine mesh" - can be obtained in more than one way. A single thing sheet of very tightly woven material or many layers of less tightly woven material. The former (fine mesh) will react poorly to pressure increases and redirect to vent said pressure; the latter (if the coarser mesh doesn't get extreme) doesn't have the problem with pressure (by comparison) but does effective trapping of droplets as the wend through the contorted path between mouth and "outside", trapping droplets on the fibers during many collisions.
Somewhere in this is an optimum for, in particular, the purpose that masks are recommended for the general public (vs. surgery): to prevent the wearer from infecting others.
This, of course, is a gedanken experiment. However, give it some thought - consider cases both at the boundaries and some middle-ground cases.

Yes all politicians have the innate ability to understate the obvious, waffle on to avoid spending, until it is quite obvious that is what they will reluctantly have to do, at which point their first instinct is to blame someone else.

Tell me about it....
Why is it all the good ones though..... Never any of the S**t actors. Same with Musicians... all the good ones, never the bad ones
The first time I ever saw the Guy Act was in the film "FX. The art of illusion", followed by FX2 then after that he just seemed to start popping up everywhere in TV programs, short films, long films, he nearly always played an authoritative figure such as a police officer, or some one that you needed to be cautious of because he could crush you any time he wanted to.
He will be a sad loss.

Exactly, why not Jeff Goldblum or Justin Beiber?

Well Jeff Goldblum would not be on my list and no... not for the reasons your thinking
But yes... exactly my point.

I watched about 1min 22 seconds of that. Am I the winner? No one else watched more than that did they?
I believe Kent owes me an Official No-Prize as the World Champion Watched-the-most-of-that-video Winner! I'll look for it in the mail.
