There are quite a few videos and experiments online that show the benefits of wearing a mask by holding a petri dish in front of their face while talking, singing, coughing etc., once with a mask and once without a mask. However, I have realised that while wearing a mask, despite the mask doing a good job blocking water droplets in the front, a lot of my breath (i.e. water droplets) goes to the sides of the mask.
Given that authorities are saying that the virus is airborne, I would think that the water droplets that come out of the side of the mask matter as well, especially in an enclosed room where many people would be spending their day. Has there been anyone who has put the petri dish at the side and did the same test as mentioned earlier? I can't seem to find any, but then again, my researching skills are not the best.
