How do you build an episcope?

An episcope is a device used to project images or objects onto a surface, typically used in educational settings. To build one, you need a light source (like a lamp), a lens to focus the light, and a flat surface to project the image onto. Place the object you want to project on a transparent or semi-transparent surface under the lens, ensuring the light source illuminates it adequately. Adjust the distance between the lens and the object for optimal focus and clarity.
