I saw it in a video but it didn't say what they put in it.

any of the alkali earth metals, most often the element that is used is sodium or potassium but francium, lithium, rubidium or cesium may be used as they are all alkali earth metals

Although electrolysis is the common way to dissassociate water into Hydogen and Oxygen, highly reactive metals, usually potassium or sodium can also be used to make a reaction similar but not exactly like disassociation.

Na + H2O -> NaO +H2

Hydrogen is liberated, but in this reaction, the oxygen is not.

Many of the "water car" and similar hydrogen scams use this process. Adding water to a black box and having burnable hydrogen come out. It is a scam because the Sodium requires lots of energy to get it to the reduced (active) state. As soon as the sodium in the black box is used up, it doesn't make any more hydrogen.

This is a very expensive and difficult way to make hydrogen. Much more expensive than electrolysis which is already too expensive to be competitive for fuel production.

There are some options to attempt this. the most consumer-friendly approach is electrolysis the position you dissolve a salt contained in the water and then you run a contemporary by the water. the present will wreck down the water molecules and Hydrogen and Oxygen will bubble up from the anode and the cathode. Be incredibly careful because Hydrogen is amazingly explosive.

Potassium and sodium can tear a water molecule apart. But they instantly combine with the oxygen. and leave hydrogen which unites with oxygen in the air, (i.e. burns) because the first reaction produces so much heat.

its called electricity or you could try using an alkaline earth metal

Salt and a 9V battery will do the trick.
