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.
When hydrophobic molecules are solvated in bulk water, possibilities for resolving some of the frustrations in the hydrogen networks appear.
Therefore, the thermodynamic properties of pure hydrogen or helium can be calculated directly with the help of a relatively simple interpolation code.
In general, a number of independent experimental observations confirm that the rt-plasma is due to a novel reaction of atomic hydrogen.
