This cough test shows you just how effective your mask is at protecting you from the virus
Take a look at exactly how effective a mask is at protecting you from germs. This simple experiment shows why researchers, health officials and government officials have been pushing for people to wear masks.
from blue polos to blue lab coats and gloves, we headed down to Sacred Heart's laboratory to unmask a common question. What exactly does a mask do? So we teamed up with the hospital's microbiology director, Dr Rich Davis. This one will be no mask. It's a demonstration of where respiratory droplets go and how they're easy. They are to transmit and how mask is effective in blocking those that's really the key take away. Here's how this demonstration worked. I had a Petri dish in front of my face as if it's another person's face. Then, with and without a mask, I talked a How you doing? Saying some body wants todo coughed and sneezed. Dr. Davis put the dishes in an incubator, and we waited 24 hours for our results. So these are the plates that you were interacting with yesterday, with or without a mask. Let's start with the face to face demonstration mask on the left. No mask on the right. Let's go with talking first with a mask. Looks good talking without who? Okay, I'm actually shocked there's any at all gonna be completely honest here. Next up singing this was changes by to park and this was smashed. Things will never be the same day. A pretty similar to talking. So now we've got coughing. So So this was just too too costs. Really. It's crazy. But those droplets were nothing compared to the ones from sneezing. First mask on. Okay, this is no mask. Who, when I had my mask on no yellow dots. But when I didn't there was always something. Think we're coming into a new reality where masks fit into that very social conscious paradigm. You do simple things that everyone conduce. Oh, it's not going to be 100% effective. But if we all do it, it's going to definitely make a difference in preventing things from spreading one person.
