Seeing is believing: Effectiveness of facemasks

Seeing is believing: Effectiveness of facemasks: Using flow visualization, researchers assessed the efficacy of facemasks in obstructing respiratory droplets. Loosely folded facemasks and bandana-style coverings provide minimal stopping-capability for the smallest aerosolized respiratory droplets. Well-fitted homemade masks with multiple layers of quilting fabric, and off-the-shelf cone style masks, proved to be the most effective in reducing droplet dispersal. Importantly, uncovered coughs were able to travel noticeably farther than the currently recommended 6-foot distancing guideline. Without a mask, droplets traveled more than 8 feet.  (News Release, EurekAlert!; June 30, 2020)
