The Milwaukee Journal – Apr 23, 1939         Darn Clever, These Sound Effects Men    CLEVER, these sound effects men. They’re not merely content in inventing a gadget for a given sound; they make the same gadget do for many sounds.    Knives and forks, for example, are used not only in eating sequences, but in exciting dueling scenes as well.    A compressed air tank used for decompression hisses, can give the illusion of a tinkling bell buoy bobbling back and forth at sea. All you have to do is strike the side of the tank with a soft mallet.    Squirting a seltzer water bottle sounds over the air just like turning on the water faucet. The seltzer bottle doubled in a comedy scene on a recent “ Town Hall Tonight ” broadcast when FredAllen  used it to produce the sound of milk strumming into a pail.
