Mirror Box Multiplies Images
ANY boy can build one of these mirror-scopes at a small expense, and for his efforts see, when looking through the peephole, three miniature objects increase to a multitude.
Here is the way it is done. Construct a wooden box about two feet long and five or six inches square. Against the inside of the front fasten a mirror as illustrated in the drawings above and drill a small peephole about two inches from the bottom. Also scratch a similarly sized peephole in the silvering on the back. Then cut a hole six or eight inches long in the top of the box and fit into it a piece of ground glass to admit light.
The rear is built up of two pieces of wood as illustrated in the accompanying drawings. Attach a second mirror to the inside of the end, then hinge the latter as shown. Paint the inside of the box white and you are ready to install the figures.
Many miniature images can be purchased at the five and ten store. Arrange not over four figures in a nice grouping. Close the end and it will seem as if hundreds of images inhabited the box when you look through the peephole. Images of ships, men, animals, etc., are recommended.
