They filled one end of a brass-and-Pyrex tube with a mixture of ammonia, methane, ethane and water vapor-all probable ingredients of the earth's early atmosphere. A thin plastic membrane separated the gases from the other end of the tube, which contained chemically inert helium. The Bar-Nuns increased the helium pressure until the membrane broke. This produced a shock wave that swept into the gaseous mixture at high speed, momentarily creating temperatures...
