��A Sausage Dealer Out-Pigs the Pig in Hungry Berlin

HAVING tried a substitute for almost everything, the Germans, we are told, are stopping short of nothing in their attempt to make certain new foods take the place of those made scarce by the war. The latest report says that a sausage dealer in Berlin has been fined $500 for selling sausage made of macerated rubber, finely ground hair and gelatin. His camouflage product contained no liver, no flesh foods and no fats. At that, it was probably as digestible as some so-called sausage on sale in this country.

Shoot Your Streamers with a Gun and Save Your Arm

A WOODEN gun, with a stock and barrel not unlike the first archer's pieces ever used, but withal an improve- ment on the schoolboy's "bean shooter," has been invented by Jose L. Cas- tillo, of San Francisco, California, for hurling long streamers or serpen- tines over the heads of people at carnivals and outdoor festivals. Elastic bands take the place of gun- powder and the barrel is nothing more than a slide, traveling in a groove. To shoot the streamer, you place it against the slide and fasten the hook or trig- ger over a stop, which takes the place of a trigger. Elastic bands afford the tension and the instant the hook is released the slide with its streamer shoots for- ward, the slide striking a forward stop and the streamer continuing on until it breaks. Before firing, the streamer is fastened to a clip on the stock.

It is well to unwind the streamer a few inches before it is fired, to prevent it from breaking off short.

��where large amounts of liquids are handled, the siphon, devis- ed by Charles Barrow and John Karpen, of Racine, Wisconsin, will, be ap- preciated because it does away with the lifting of heavy bottles. With his siphon, the chemist inserts the ends of two tubes into the large bottle and places the other ends into the bottle to be filled. One tube contains a large rubber bulb. The sec- ond tube contains only air.

When the bulb is rapidly compressed, the pressure on the top of the liquid in the end of the tube is reduced. The greater pressure on the top of the liquid outside of the tube forces it toward the in- side, then up and into the smaller flask.
