Maybe as a kid one of the usual items in your pocket was a hand lens. I was given one as present that folded into a leather case. It saddened me when, a few years ago, I had to discard it. Both the lens and the case were falling apart. There is a fascination in viewing the small world.
That fascination continues in science with tools that I never imagined. Earth Science Picture of the Day (EPOD) is celebrating its 20th year with an EPOD from the past. The September 5th image was first posted March 17, 2004 and shows morning frost on a blade of grass. The "hand lens" used is a low-temperature scanning electron microscope."
