What is dirtier, your phone or your toilet? (Patreon)

First results are in! Of the 10 tested things so far the terrarium is "dirtiest". It has a lot of bacterial colonies on the plate. They are not necessarily bad bacteria. Surprisingly the plate of the phone had no growth yet and the one of the toilet had only 2 small bacteria colonies. But this is only day 1, need to give it at least 4 days.
