Did anyone see people claiming that you could make beef jerky without heat, just using two box fans and two paper air filters?
I could not find paper air filters then and I cannot find them now. Nobody who likes you would recommend using fiberglass air filters, but I have wondered: If you duct-tape a 20x20 MERV 12 filter to a box fan, how much air would actually go through the filter? The thing is pleated like crazy, which was my idea when people started making their own masks. A good mask is restrictive!
Pleat it!
How much air would go around the filter?
I would like to see the math on holding choir practice on a hill on a windy day. I am pretty sure that you are still doomed. How about a field on a hill on a windy day? How far apart do you need to stand if you are singing?
How much more at-risk are people on the leeward side versus the windward side?
I got it! Hollywood Squares had the answer all along!
Only you need really deep squares! Stack 40' conexes, have the singers stand in the back with a light, and have the director stand on a platform that is half as tall as the conex stack and far enough to see everyone!
Why isn't every choir doing this?!
