My 1991 high school chemistry project on electromechanical cells. Brought to you by Commodore Amiga 500, Okidata, ProWrite and Digipaint III:

I drew the battery on page 5 by hand in a raster-based art program called DigiPaint III. In 1991 that was quite a feat. Today, kids would probably just search for the image of a damn battery on Google Images.
