Show MAKE YOUR OWN SNOW. tu C-riont Formation In th Full Rays of a July San. . j Two solid bodies, one yellow, ralptrar, tlie other black, carbon, unite under certain cer-tain circumstances to form a colorles liquid called sulphide of carbon, which must be handled with much precaution on account of its great explosive prop erty. The soluble property of sulphide of carbon renders it valuable to take spots off of garments. If its odor ifl more disagreeable than that of benzine or turpentine, it has at least the advantage advan-tage of being dispelled quickly in consequence conse-quence of the prompt evaporation of the liquid. There is nothing equal to it to take oft ppots of paint on clothes. 14 does not do it, however, without creat ing great fear in persons who use it for the first time, for they see on the very place where, to their great pleasure, the paint had disappeared a large white Fpot, the nature of which is hard for 1 them to define, and the more they brush the more unsightly and the larger that white spot grows. Is then the garment lost? No, for fortunately after a few s moments the spot melts away never to show again. It was 6now and nothing more. The sulphide of carbon in evaporating evapo-rating takes heat from the cloth and lurrounding air, and the result of thai is a sudden lowering of temperature sufficient suf-ficient to freeze the vapor of the atmos- j phere. I "Without operating on your clothes you may make the experiment in the following way: Fill a small vial with sulphide of carbon, taking great care tc do it far from all flame or heated stove. Then close the bottle with a cork stopper through which you have previously bored a small hola In this hole place a piece of blotting paper made up into a Email rolL The paper must reach to the bottom bot-tom of the bottle and about an inch above the cork. Within 15 minute you will see the outside of this paper covered cover-ed with snow, the quantity of which gradually increases. The liquid has risen through the pores of the paper as the oil of a lamp through the wick. When it gets to the open air, it evaporates, and the water contained in the Furrounding atmosphere, being brought to a temperature temper-ature below 32 degrees, has been frozen. If you divide the paper outside of the bottle into several pieces, you obtain flowers and most charming effects. You may make the experiment in summer and in the full rays of the sun. The result re-sult will be obtained then more promptly, prompt-ly, evaporation being more abundant t Louis Post-Dispatch. |
