In order to do something completely different than usual I got myself some Agar-Petri-dishes and sterile cotton sticks to grow some bacteria. I poked the cotton in a variety of (dirty) places and took a look at what grew out of it. These are the pictures that came out of this experiment. I can not identify the micro fauna at this moment but will keep it in mind next time I meet a micro biologist or until I have the time to study some books on the topic.

Citchen sink 24 hours	48 hours	120 hours
Cellar wall 24 hours	48 hours	120 hours
Dirty fingerprints 24 hours	120 hours	The three colors isolated. This indicates three different types of bacteria.
A cats nose 24 hours	120 hours
Human tongue. Suprisingly clean, but the agar tasted disgusting... 120 hours
