How to make soap bubbles
Monroe,!., Jane, 1894. - - V " Hlffh. Art Soap Bnbbles. THEY QAX BB HADX TO SXSVB TOR A. LOT Or TTCKXT TRICKS. Soap - bubble blowing can be made almost a fine art with the proper appliances. . , First of a'l common soap Is useless for the purpose of blowing good babbles; the best thing Is a substance known as oleate of soda, wntcn can be bought at any large drusr store. , If, however, this cannot be obtained, castiie soap may be used. In either case three - quarters of an ounce Is placed In a perfectly clean quart bottle, with a pint arwl a half of distilled water, or, falling tola, of clear rain water. This Is left for about a day, when the oleate will bare dissolved. The bottle must not be heated. When the oleate of soda has dissolved, add half a pint of glycerine and tho solution is ready for use. Now make a stand of stout copper wire by bending one end Into a circular loop no. l. about 214 inches in diameter, and fasten It either by twisting, or, better, by soldering the Joint smoothly. Then at about 3 Inches from tbe loop bend the wire at right angles and fix tae other end into a block of wood. If the loop is thoroughly wet with the soap sortition and a bubble is brought in contact with the loop It will adhere to the wire and the pipe can be removed. (See Fig. 1.) The bubble now remains sealed .on the ring and is a very beautiful object - In order to show tbe great elasticity of the bubble take a clean glass rod, moisten It thoroughly with the soap solution and push it gently through the sivle of tbe bubble. The rod may be passed completely through the film ana withdrawn without Injury to the bubble if properly wetted with the solution. Nest take about 6 inches of glass tube having a diameter of half an inch; dip one end in the solution and blow a bubble upon it. On removing the tube from the mouth the bubble 1 nists with such vlloence that on bringing a lighted taper to the mouthpiece the flame is at once blown out. To still further show the elasticity ot the soap film, get a few inches of aluminum wire of about the thickness of a small pin. Bend it into a circular loop of about 2 Inches in diameter, and leave sufficient wire to form a handle as In figure 2. Now take the pipe and affix a FIG. 3. bubble to the under side of the copper ring, detach the pipe ami remove the small drop of liquid which adheres to the under surface of the bubble by touching it with the tip of a moistened glass rod. Next moisten the aluminum ring and gently apply it to the bottom of tbe buuu.e, to which it will at once attach itself. Then take some V - sbapod slips of thin paper to act as weights and suspend them one by one upon the handle of tie ring. If this is carefully done quite a large number of inem may be added before the combined weights of ring and paper cause the bubble to break. (See Fig. 3.) When we consider the thinness of the films their tremendous strength is mat - no. S. velous. The finest gold leaf is 400 times thicker than the film of a soap bubble, while It would require 282,000 of these gold leaves to make a pile of one inch (n height. The lightness of the bubble may be finely show? thus: Attach t'ae pipe to a gas burnei by means of a rubber tube, dip the bowl of the pipe Into the soap solution, withdraw the pipe and allow the bubble to fill with gas, the flow of which can be regulated by pinching the tube. These bubbles fly up to the celling at a great rate, and may be set on fire as they ascend. Now allow a gas bubble to iorm on the pipe, but before It detaches itself apply tbe moistened aluminum ring, to which has been fastened the end of a piece of sewing cotton, some two or three yards In length. The bubble will carry up with it the aluminum riug and cotton and remain floating in mid air like a captive balloon. These are only a few of many experiments which may be made with the soap bubble. Others equally interesting and wonderful will suggest themselves.
