Conditions of Use
So... me and my group decided to swab the door handle, lunchroom table, toilet seat, and the locker room locker for bacteria. We made a bad mistake when we put the bacteria in the container because we broke the agar that was at the bottom of the container. it broke in all the sections except for the toilet seat section. 24hrs later after we stuck the petrie dish in the incubator we found only one small speck in the toilet seat section. we believe that it didn't grow anywhere else because we broke the agar which was the food, which made it so the bacteria couldn't eat..we found out that bacteria cant feed of plastic...that is all for are observation:)

Justin- that's probably because there's water running downvthe urinal. Cleaning the pee with every flush.
Katherine- that really sucks that you broke the agar. I would've been interested in hearing your results!
