ABOUT

Unilever soap brand Lifebuoy has come up with a radical way to remind us of the importance of handwashing -- growing cultures from everyday bacteria and turning them into outdoor ads.
Innovation group The Electric Factory extracted bacteria and fungi from a variety of common items, such as household bills, banknotes, games consoles and smartphones, then placed them in a giant, custom-built petri dish and cultivated them for days at a time. The cultures, and the objects, were then displayed as posters in shopping malls.
