The gas used in the balloon is helium, which is not explosive like hydrogen, and therefore not as dangerous. The water coming through the vents is very rich in chemicals like hydrogen sulfide. These “ships of the sky” had a long metal frame covered by material that was then filled with a lighter-than-air gas, normally hydrogen. Water is made up of two chemicals, hydrogen and oxygen. hydrogen | American Dictionaryhydrogen noun[ U ] us/ˈhɑɪ·drə·dʒən/ physics the lightest gas, one of the chemical elements, and having no color, taste, or smell Examples of hydrogenhydrogen When hydrophobic molecules are solvated in bulk water, possibilities for resolving some of the frustrations in the hydrogen networks appear.
