Where do the bacteria in our everyday environment come from, and how do we make them visible? Visitors can imprint a fingertip or a clean everyday object (e.g., phone case, bracelet) on a prepared agar plate. We explain sterile working principles, why colonies form, and what can (and cannot) be concluded from colony appearance. We will show several plates prepared in advance so visitors can immediately see different colony patterns and colors.
