From Colossal: The Microbes on the Handprint of an 8-Year-Old After Playing Outside.

We all know our bodies are home to countless millions of bacteria and microorganisms, but without seeing them with our bare eyes it’s almost impossible to comprehend. This petri dish handprint created by Tasha Sturm of Cabrillo College, vividly illustrates the variety of bacteria found on her 8-year-old son’s hand after playing outdoors. The print itself represents several days of growth as different yeasts, fungi, and bacteria are allowed to incubate. [blockquote]

This is about eleventy million times cooler than plaster-casting a kids’ handprint. So interesting! The photos of the bacteria make me want to drop everything and become a bacteriologist.
