cant find tread / link

[rexst]

somewhere amongst all the virus posts and threads on here - someone had posted a great link to a study showing how easily and shockingly a virus can spread in a social setting

- the study had an invisible 'virus' that would show up under black light - results were shocking

- i would like to find that link, but i have tried searching with many key words with no luck

- can anyone direct me to it?
