I don't know exactly what one would do with this pocket microscope, and, come to think of it, I kind of don't want to know. But I think you could have some fun examining the natural world super close. Remember looking at every leaf, bug and snowflake under the microscope when you were a kid? Well now you can do it again. When ever you want. And the teacher can't tell you to stop fooling around. $9 at Exit 9.
