Devices for super-saturated H2 water. a and b Method I: A PET bottle, in which a gas-permeable film containing H2-generating agent has been directly inserted, is filled with water and then tightly closed. The H2 gas produced is emitted into the water in the bottle, lowering the height of the water level, which is then gradually pressurized by the gas. After the reaction is terminated, the H2 gas is dissolved by shaking the bottle. c and d Method II: The non-woven fabric containing H2-generating agent is first inserted into an acrylic resin tube, and 0.5Â mL of water is added. The tube is inserted into a PET bottle filled with water. The H2 gas generated in the tube is then transferred to the bottle through the valve
