the mouth of the bottle an apple, (Fig. 33). It seems quite an impossible feat, but it is readily accomplished.
Another curious experiment in equilibrium is the following: Take a couple of forks and arrange them with their prongs one set over the other, and stick a silver dollar between the middle prongs, thus uniting the two forks. This accomplished, place the coin flat on the rim of a tumbler, pushing it outward until the two circumferences touch externally. The coin with appendent forks will remain balanced much to

You may follow this up by pouring the water steadily from the glass into a second glass, without disturbing the money or the forks, which remain in equilibrio. The above clever feats may properly be performed at the dinner-table after dessert has been brought on.
