A Sanitary Drinking Tube
To make this tube, procure a piece of ³⁄₄-in. gauge glass, about 10 in. long, and bend it by heating the glass with a blowtorch 2¹⁄₂ in. from one end, as shown. If this is done in a place where no air will strike the glass while it is heated and the tube is then allowed to cool slowly, it will not crack. It is used by putting the short end under the faucet and drawing on it as on a pipe.
