Re: water in a vacuum

Well, I think the volume of ice shouldn't change after the initial freezing and capping. It is true that he would have produced a lower pressure area in the pipe after it was thawed; however, that's not much of a vaccuum....

> he thought for sure he was effecting the 106 degree angle of the hydrogen atoms. so many claim to be able to do this, but who knows?
Have a look at this site: http://www.lsbu.ac.uk/water/molecule.html

It does say that the bond agle can fluctuate, which makes some sense given that the molecules are moving around quite quickly and can move relative to each other (making the whole molecule flex). That said, this flexing is time dependent and happens extremely quickly, so I doubt it's possible to permanently change the bond angle of water.

If your friend really wants to produce large amounts of hydrogen, he would do best to set up some sort of electricity generator (solar panel array, wind turbine, or tidal generator) to electrolize the water directly. Tweet
