When swimmers compete at the highest level, the lactic acid that burns throughout their bodies creates an imbalance of of blood, saliva and other necessary fluids. Olympic pools are fortified with more than chlorine and muriatic acid in order to make up for this deficiency. Operating as a sort of oral mouthwash, the vitamin-enriched pool water is swished around by swimmers and absorbed into their bloodstream through a membrane in the cheek. It is then expectorated in a spraying fashion in order to disperse the broken down chemicals into the water. The additives are made by the same company that distributes Flintstone vitamins. Thus, the pool at London’s Aquatic Centre tastes like a red Wilma.
