During mid covid I did a demo for my kids. A sheet of paper and a spray bottle. Test 1, spray from 2 feet. Of course the paper was soaked. Test 2, a cloth mask placed on the paper. It gets damp, especially if left in place. Test 3, a cloth mask over the spray bottle. The mask blocks almost all of the spray. We did not bother with test 4 (2 masks) after the 3rd, but I think they understood the point. We did retry 3 with a medical mask, with 0 spray through.
