VOCs  don't build up behind the mask, but your own bad breath is hazard enough since it only contains about 16% oxygen and over 40,000 ppm CO2.  That qualifies it as a hazardous atmosphere.

What did we learn from the video? My take-away is that VOCs do indeed build up behind masks, which is a concern that has been expressed before. This demonstration has nothing to do with the dynamics of how coronavirus might be contained behind a mask or spread without one. This demonstration reminds me of the demonstrations that Dr. Oz performs on his show - demonstrations that have nothing to do with the phenomenon being described except to provide a visual. "Look at how the fat melts away!"  (it was some kind of water soluble starch or something being doused with water....).

I think this will be a huge help in communicating with those who might dig their heels in.

Thanks!

It certainly does make a point! I was a bit curious about the video creator, especially given his "see you in a couple years" sign off and the response in some of the video comments. Turns out he came out of "retirement" to make this after not posting a video since September 2017.

Just my kind of video.  Thanks a lot of fun.  Thank gosh it was done outside.  Not a demo for the faint of heart.

I just ran across a mask effectiveness video you may find interesting.
It's not one of those lab coat/goggles professional type ones. This one
is aimed at a more blue collar audience and definitely gets the point
across.
 
It's not something you would do for a class demo. See how many safety
issues you can find.
 
 
Cheers!
