Bacteria
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.
