  Here is one more trick of equilibrium, which appears to be interesting enough to find a place among these experiments. We need not give any long explanations, for our figure fully illustrates the way in which it has to be executed. First place a knife straight before you, then two others which you place, blade upon blade, over the first. Finally, the two last ones are arranged transversely, their blades passing over those of the two knives put down in the second instance, and below the blade of the first knife. By taking hold of the handle of the first knife, you can lift them up all at once without breaking the equilibrium. |
