Cheap plastic box camera, 127 (IIRC) roll film, won as a prize for drumming up subscriptions for my paper route. Inexpensive microscope, birthday or Christmas gift. Cardboard tube from some kitchen "paper" (maybe foil, maybe waxed paper). Sheets of foolscap, cut carefully along the lines to form strips. White glue.

Edmund Scientific: individual lenses of great variety (presumably they got them by stripping out of WWII surplus equipment). Small piece of ground glass.

Wind strips round and round lenses until the OD just fits inside the cardboard tube, then white glue on the two faces to form the adapter for that lens. Repeat for other lenses. Same for the microscope barrel, to fit the tube over it (two adapters, top and bottom, to keep the assembly straight), and one for the plastic ring forward of the camera's lens.

Assemble the "extension tube" and lens, mate to microscope and camera, ground glass in the camera back for focusing. Film, microscope slides, click/wind, repeat. Photomicrography on a tiny budget! And the start of a lifelong mild interest in photography.

OH yeah!

With a 4.25 in. spherical mirror, combo secondary mirror holder and eyepiece holder, a piece of irrigation pipe became a telescope! On my almost zero budget.
