What tiny creatures are living in the street puddles or pond water where you live? You can discover them for yourself using a smartphone, some poster tack, and a laser pointer. In this episode of Gross Science, Anna Rothschild shows us how to create a DIY phone microscope at home.
Check out a variation on this experiment here: Turn your smartphone into a digital microscope. Plus, watch and try more microscopic adventures, including: Animated Life’s Seeing the Invisible, Gary Greenberg’s microscope photography of sand grains, a DIY microscope made out of LEGO, and how do you find water bears (tardigrades) in the wild?
