At one apex fit a nozzleand cork; at the other, make several minute openings. Cover the holeswith sealing-wax, and draw the cork; then fill the jar with H, and replacethe cork. When ready for use, hold the jar in a vertical position, removethe wax from at least one orifice, ignite the H at that point, and draw thecork. Still hold the jar quietly, and in a minute or two the tiny jet of Hwill begin to sing like a swarm of mosquitoes, buzzing and humming in amost aggravating way until, unexpectedly, the fitful music ends in a loudexplosion. 44 INORGANIC CHEMISTRY. over a minute jet of burning H. At first no effectwill be produced; but as we slowly introduce thejet farther and farther into the tube, a faint soundis heard, apparently in the far-off distance. It grad-ually strengthens, and finally bursts i
