Spherical Lens Microscope

This is a replica of Antonie van Leeuwenhoek's spherical lens microscope and is part of the Learning in a Makerspace chapter of my new book "[The Makerspace Workbench](http://shop.oreilly.com/product/0636920028147.do)" from Maker Media! Cut the pieces out of 1/8" plywood, create a small spherical lens (directions are in the book), add 4-40 and 2-56 fasteners and see what you can see!
