Water Astronauts required water for drinking, washing, and food preparation. Fuels cells in the Apollo spacecraft provided most of the water for astronauts' needs. Fuel cells create electricity by combining hydrogen and oxygen, producing water as a byproduct of this process. A portion of the water supply was chilled for drinking and food preparation. The rest was heated for use in hot meals. Watergun This device dispersed cold water aboard the Lunar Module on Apollo 11. Lent by Buzz Aldrin Chlorination and Buffer Ampules Chlorine in these ampules, carried on the Apollo 11 flight, prevented the growth of bacteria in the spacecraft water supply. The disinfectant periodically was injected into the water system and, after a short time, the buffer solution was added to the water to neutralize the chlorine. Clothing and Accessories
