As an engineer I tried to explain this to people about size of the pores in a mask this way. I have a fishing net, with 6 inch spacing. What do you think my chance of catching a fish smaller that 6 inches in a frontal diameter (girth)? Zero. Of course, maybe fishes that are longer that 6 inches will be caught, maybe not.. you would be am…

What do you think my chance of catching a fish smaller that 6 inches in a frontal diameter (girth)? Zero. Of course, maybe fishes that are longer that 6 inches will be caught, maybe not.. you would be amazed how people did not get it.. So, went a little more obvious. A golf ball is roughly 1 inch in diameter, and I asked how many golf balls with 1.5 in diameter would you be able to hold? Incredibly, some people said 50%.. My mind literally exploded. Apparently, our country is full of complete imbeciles.
also an engineer. My analogy has been: "consider how hard it would be for a mosquito to pass through a cyclone fence?" That usually wakes them up. (However, it is probably a white lie by a factor of two!) 0.1 micron vs 0.5 micron holes or 0.2" vs 2" cyclone fence holes.
Exaggeration can be useful to at least cause lucidity in the blind. Later, offer reality.
