Use a Drop of Water as a Macro Lens for Phone Photographs

Carefully place a drop of water over your lens, carefully invert the phone, and voila — instant macro shots with the cheapest lens you’ll ever own. Alex Wild over at Scientific American has more details on the technique and some great sample shots taken with it.
