Split Needle Causes Echo on Talking Machine
An amusing stunt is to split the end of a fiber talking-machine needle carefully about ¹⁄₄ in., so as to make two points, slightly separated. The needle is then placed on the machine, preferably on an old record, so that the points play the record successively, producing an echo. If the work is carefully done, and the points are separated slightly, both reproductions will be fairly clear.—Frank Murphy, Faribault, Minn.
