Andy Buckram's Tin Men

Empty cans can be useful in a number of ways. They are good for holding worms when you go fishing, and the large ones are fine for bailing a leaky boat. But even more interesting are the many mechanical things that a clever boy can build out of cans. Andy had made doorstoppers out of cans full of sand. He had made cowbells out of cans, with clappers which he fashioned from jointed wire and small stones. Then Andy read about a boy in California who built seven robots, one of them six feet, ten inches tall. It is not easy to build a robot, and only very clever boys should try it. But if the boy in California could do it, why in the world should not Andy Buckram do it too? The answer, of course, is that Andy did.
