Nifty experiments and mesmerizing clip art from vintage chemistry manuals

Evil Mad Scientist has a great collection of photos taken of the booklets that came with the sort of old-fashioned, you'll-put-your-eye-out chemistry sets regularly sold to children in midcentury America.

It's a treasure trove, not only for those of us interested in science, but also for anyone with a special place in their heart for the era's graphic design.
