Not all masks offer equal protect to slow the spread of the coronavirus. To demonstrate how different each mask is -- a homemade mask, a bandanna -- researchers created a visual simulation. 

<p>these researchers were not trying to create the perfect model of droplet Marisol. Spread through masks, they really set out to create a practical and visual demonstration of the performance off three different masks, a mask made of a folded handkerchief. Ah, home made mask made of two layers of cotton and fabric and a simple dome mask. Have a look. Using a mannequin head and fog maker to create a visible aerosol highlighted by a green laser, the researchers created a simulated cough. Ah, light cough without any face covering spreads the aerosol mist a short distance, but a simulated heavy coughed without a face covering expelled aerosol three feet away within two seconds and six feet away by 11 seconds. They also showed the effect a light breeze had on the aerosol spread. While the breeze does disperse the aerosol, it moves the particles down wind now, looking at the spread of the air, assault with a folded handkerchief or bandanna to block it, you can see that it leaks a significant amount of air assault through the mask face and at the top edge, using a home made stitched fabric mask with a simulated cough, found a much better reduction in the amount of aerosol spread into the air. The spray doesn't go much beyond three inches from the mannequin face, but there is still leakage at the top of the mask now. Finally, the researchers used in off the shelf cone type mask. It's important to point out that although it has the same shape as some N 95 respirators, this is not an N 95 respirator now. Interestingly, the amount of aerosol that penetrates the front of the mask travels farther than the aerosol from the hand sewn mask, and again there is leakage from the top of the mask.</p>

<p>Hi, everyone. Meteorologist Anthony Baglione here on this Friday where we're still looking at some relatively warm temperatures into this afternoon. 83 is where we should hit for a high temperature. Nice and quiet for us until we get later on into late this afternoon into this evening where we're gonna watch the potential for some showers and storms coming through. Not a ton of activity for us as we head later on into tonight. There's a look at rain chances though. They go up to about 50% as we head into that evening time frame. So if you have any plans tonight, if you want to go out and get a Friday evening dinner or something like that, it might be a good idea to a, get the indoor table and then b bring along the reindeer just in case tonight. Here's a look at Future cast. So we time this out looking pretty quiet here the next couple of hours that band back to our west, it should start to weaken as it gets closer to us. It may try and restrengthen them as we get into. Like there's four o'clock you can see on Futurecast 56 o'clock or so, some of those storms could be on the stronger side and then it pushes out of here as we get later on into tonight and then we see maybe a stray shower potential still outline for tomorrow morning. Here's a look at our severe potential today. Level one out of five for most of the viewing area. What this is saying is there could be some isolated pockets where we get some stronger storms. It looks like the best chances for that would be west of us. But gusty winds would be our primary threat as we get into this evening. 78 is where we go for our Saturday. A huge temperature swing there into Sunday at 59 scattered showers are gonna be likely though, especially Sunday afternoon into Sunday evening, they do start to taper off though late Sunday night. So for the Tar Heel 10 miler, that's tomorrow morning, we are proud partners of that. We're going to see temperatures in the sixties for the majority of the forecast there. A stray showers possible, but most of the morning is looking just fine for that event. Tomorrow. We head over the next seven. We go from 83 today all the way down to 59 on Sunday. A rebound of 66 on Monday and then a nice week next week attempts in the seventies, even a few upper sixties there Thursday looking pretty quiet after we get some rainfall there to close out our weekend.</p>
