Even if you abhor science, this is actually pretty cool. It's a pocket microscope, weighing in at slightly over an ounce. It has a built in white LED for light and a magnification level of 60x up to 100x. After opening up the box it came in with a plastic knife, I promptly examined my carpet floor (it was a plastic knife; I was tired and resting, ok?) I saw all these cool plastic like fibers - cool! Really, it's fun to look at things close-up. I don't know if I would walk around with it but it's nice to have around, and only a bit over $10.
