IMO water doesn’t have hydrogen, which is H or H2. If you put hydrogen in water it would float away and no longer be in the water (at STP). (Tbf, there are hydrogen ions (protons) in water, which determine it’s pH, but like 10^-7 for pH 7, and this is a dynamic equilibrium.)
I didn’t watch the whole video but the woman stuck me as someone who would believe anything, which is an alarmingly high portion of the population. (Hence Trump.)
