Illustration A shows a design composed of a solid rubber handle attached to a clear glass blade. Illustration B shows a design of a clay handle which is apparently driven through a wedge of Swiss cheese. (This is what designers call a delicious solution.) Illustration C merely reverses the material; the blade is now made of wood and the handle is made of steel. Illustration D depicts the handle made of plastic (ordinary polystyrene), and the blade made of granulated sugar. Illustration E depicts the handle made of bamboo and the blade of cast concrete. With these illustrations, I conclude this experiment aimed at provoking a personal response.
