In this work we present a simple way to get macro photography (enlarged photographs) using a tablet or phone. We initially discuss the technique, which is essentially the accommodation of a drop of water on the camera lens. Next, we explore some applications to science teaching at elementary and high-school levels. As it is discussed in the text, due to the simplicity and power of the technique, it may be a good teaching tool for using in various disciplines, such as science, biology and physics.
