How about very low-tech toys made by a very high-tech machine?
I used to operate an injection molding machine, making various objects that were used on seismic cables. Among these objects were different kinds of plugs that were spaced every so often along the cable, to which would be attached other equipment. In a way, it was like plugging in a lamp or a toaster, although the plugs and the connectors were quite different.
One of the plugs I had to mold (we called this kind a “drop”) bore a remarkable resemblance to a mouse–a small thin part where the wire went in, widening to a round cylindrical shape about an inch in diameter. A mandrel attached to the connectors in the mold, and kept the plastic from shooting out the end of the mold. It also had a pin that reached through the length of the mandrel, which held the connectors in place while the plastic flowed. Typically, a drop would be maybe two to two-and-a-half inches long.
Anyway, when I set the machine up to shoot drops, I always made a test shot or two, just to make sure the mold was positioned correctly and the plastic was flowing as it should be. These test shots had no connectors in them, but I did use scrap wire and a mandrel, just to keep the liquid plastic from flowing out and on the floor. Some would always escape though, through the pin hole in the mandrel, and these test shots would have a three-inch “tail” of plastic that had flowed into and through the pin hole.
So once I trimmed the sprues off the finished test shot, we were left with something mouse-shaped, with a long tail. Rather than just throwing the test shots out, I’d bring them home, for our cats to play with. They loved them, especially on the kitchen floor, where they would make a satisfying “clunk” as they rolled.
This isn’t a terribly clear explanation of the injection molding process nor of the drops themselves, but the important thing is that our cats liked their “drop mice,” as we came to call them. Drops are practically indestructible, and our cats, who are very good at destroying toys, can still play with their drop mice, and probably will for years.
