10.--THE BALANCED PAIL OF WATER.

[Illustration]

Fig. 10 looks a little startling! There is, however, no risk if the

experiment is properly conducted. The requirements are: a kitchen table,

a pail of water, a stout, flat stick three or four feet long on which to

hang the pail, and another and slighter piece of stick. The larger stick

is first laid upon the table with about one-third of its length

projecting over the edge. The pail--empty--is next hung upon the

projecting end of the stick. The smaller stick is then placed with one

end against the inside angle of the bottom of the pail at the point

nearest the table, and the other end cut away at such a length as will

permit it to wedge tightly against the under side of the main stick, at

which point a notch may be cut in the latter to prevent slipping. The

whole bears a structural resemblance to the balanced ladle of Fig. 9.

The pail may then be partly filled with water, when it should remain

balanced as in Fig. 10.
