The sick men were unencumbered and could freely touch the cards, the chips, or their own runny noses. The men were seated about 4.5 feet from one another.

Since the healthy men couldn’t touch their faces, the only way they could get sick was by breathing in airborne virus particles expelled by their unwell poker buddies.
Once this first part of experiment was over, the presumably cold virus–infested playing cards and chips that the sick men had handled were immediately transferred to a new lab room, where a fresh batch of healthy volunteers was waiting. These men played poker with the cards…
