A 2008 analysis of unpublished results from this experiment found that use of a tapered aspirator to increase airflow to the main vessel improved the results.  
A 2008 analysis of unpublished results from this experiment found that use of a tapered aspirator to increase airflow to the main vessel improved the results.  The experimental setup contained an oxygen-free closed loop of sterile glassware, with one flask connected to a pair of electrodes applying a continuous electric current. This experiment was designed to test the hypothesis of Alexander Oparin and John Haldane. This experiment produced a racemic mixture from the reaction of water, methane, ammonia, and hydrogen together over a one-week period. Showing the spontaneous production of amino acids from inorganic compounds, for 10 points, name this experiment on the chemical origins of life.
