6.AB. SELF RISING POLYHEDRA
H. Steinhaus. Mathematical Snapshots. Stechert, NY, 1938. (= Kalejdoskop Matematyczny. Książnica Atlas, Lwów and Warsaw, 1938, ??NX.) Pp. 74-75 describes the dodecahedron and says to see the model in the pocket at the end, but makes no special observation of the self-rising property. Described in detail with photographs in OUP, NY, eds: 1950: pp. 161-164; 1960: pp. 209 212; 1969 (1983): pp. 196-198.

A pop up octahedron was used by Waddington's as an advertising insert in a trade journal at the London Toy Fair about 1981. Pop-up cubes have also been used.
