JUNE, 1941 THE YOUNG CITIZEN 2is AN EASY WAY TO MAKE AN HOUR GLASS sand that took exactly one hour to run through the opening into the other bulb. Then, when it had all run through, the hour-glass was reversed, and the sand ran back into the first bulb, thus measuring another hour, and so on. Any boy or girl can make an hourglass without much expense. We take two· botiles of the same size and ·shape -a shape like that shown in the illustration is the best shape. Then we take a quantity of fine sand, which has b·een washed and sifted, and put this in one of the bottles. Now over the neck of the bottle we IN ancient days, time was measured by tie a piece of rubber. from a bursted toy an hour glass.

A JUMPING FROG MADE FROM A -WISHBONE THE next time you have a chicken for " dinner, save the wishbone-the lyreshaped bone in the chicken's breast. It is quite easy to make a jumping frog from this wishbone. We take the wishbone, and first thoroughly clean it. We let it dry for a day or two. Then we take a piece of strong, thin string, and, doubling it, tie it securely to the two "arms" of the bone about a half-inch from the ends, as shown in the picture. Now. we take a small piece of wood a little shorter than the bone, and a short distance from one end cut a notch around it. ·Slip the stick half-way through the doubled string, midway between the two "arms'~ of the bone, and turn the wood around and around until the string is .twisted and. shows a strong resistance. T hen pull the stick through until the string clings around the notch. Cut out of thin cardboard the rough resemblance of a frog, and stick this with paste to the top of the wishbone. All that is now needed is a touch of glue on the und.erside of the bone. (Please turn to_ page 223.) ]UNE, 19+1 THE YOUNG CITIZEN 22j of fire for warmth.
