shot from a cannon, and toss it gently against the roof at one end of the temple, then see the columns totter and fall, leaving only a portion of the Parthenon standing, in the same way that the real marble columns fell when the original structure was shattered and practically destroyed by the soldiers.

You can

Blow Bubbles with a Spool,

beautiful bubbles, which float and glide in the air with all the charm of clay-pipe bubbles. Mix strong soap-suds, dip one end of a large spool in the water, wet the spool, then blow. If the bubble refuses to appear, dip the spool in the water again, put your head down to the spool and blow a few bubbles while the spool is in the water, then quickly raise it and try again. Nine times out of ten you will succeed, and a bubble will swell out from the spool as in [Fig. 81]. These wooden bubble-blowers last a long time, with no danger of breaking when accidentally dropped on the floor, and you can always find enough to provide one for each of the players who meet for a trial of skill in bubble-blowing.

Now try

Pretty Butterflies

which fly from spools. Cut a butterfly ([Fig. 82]) from bright-colored tissue paper or thin writing paper, bend at the dotted line and paste on the large end of a very small cork. Fit the small end of the cork into the top of the hole of an empty spool ([Fig. 83]). Then blow through the spool and see the butterfly ascend rapidly to the ceiling and float down again. A number of different colored butterflies in the air at one time fill the room with charming bits of fluttering brightness that will delight the children.
