Right, but wetting does not look like a problem.
I was thinking on good rotating parabolic mirrors and MHD applications.
It came to my mind that dynamo effects and effects from Earth's magnetic
field would alter the shape of the mirror.
Galinstan is practically too expensive to buy. It sells in common shops as a
medium between coolers and electronic component, CPU-coolers.
Surface tension would be high. It would be nice to do some experiments with
alternating surface tension with electricity. Due to the high conductivity
changes would be instantaneous.
Maybe it could be used to try the validity of Kadomtsev, Pogutse, Witalis
frozen-in law violation.

Hi David,
You are referring to Galinstan not Gaslinstan, correct?

The problem with rotating Galinstan is mentioned in the article -
Galinstan tends to wet and adhere to many materials, including glass,
which limits its use compared to mercury. Galinstan is commercially used
as a mercury replacement in thermometers due to its nontoxic properties,
but the inner tube must be coated with gallium oxide to prevent the
alloy from wetting the glass surface.
Mercury is certainly toxic, especially long term exposure, but can be
safely handled for experiments with the proper precautions.

Hi all
Experimenting with Mercury can be rather hazardous.
Now with Gaslinstan, liquid down to -19 centigrades, a lot of
experiments become possible. Too bad it is still rather expensive.
Someone mentioned strange effect when rotating mercury fast.
