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.

Every streamer would sail far and 

 swiftly if expelled from a gun 



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.
