Condensation Bands formed during the Explosion of Hydrogen and Air

Nature volume 113, page 712 (17 May 1924) | Download Citation



WHEN a mixture of hydrogen and air is exploded in a tube open at one end “water rings” are sometimes formed on the sides of the tube. This phenomenon appears to be familiar to some people, but I have not been able to find any published account of it. The accompanying photograph (Fig. 1) shows the formation of these condensation bands during the explosion of a mixture of hydrogen and air in a test tube 6 inches long, the gases being ignited at the open end.
