The chemicals were sealed inside a system of sterile tubes and flasks which were connected in a loop. Sparks were sent through the air in a simulation of lightning. Methane, ammonia, hydrogen and lightning were meant to simulate the conditions of an early Earth. After a week, 2% of the carbon had turned into amino acids including 13 out of the 21 amino acids used to make proteins in living cells.
