Water marbles
Anyone know what kind of reaction is going on here?
It is quite cool to see.

With sodium acetate, calcium bicarbonate and iodized salt and water this is achieved.

Sodium polyacrylate spheres. They sell these at the dollar store where I live.

Hydrogels  They can literally become invisible in water because they are
almost all water. I used to research them. These ones are hydrogel balls for growing plants

That was very hard to watch.
Also, the marbles would smush into each other and become one, no?. They were all exactly the same, hence the prior conclusion that they are already
marbles of some sort.

Its a sodium neutralised form acrylic acid polymer. If I had to guess I'd bet that mixing sodium acrylate and a little benzoyl peroxide together would
get the reaction going, but getting it to form perfect spheres likely involves careful control of the reaction, maybe some sort of industrial process
where the polymerizing material is turned into an aerosol to form the little spheres.

Can these absorb anything else besides water? Im trying to see if they can absorb any flammable solvent, and have had no luck so far.
Ive tried Acetone, Methyl Ethyl Ketone, Methanol, Toluene, Ethyl Acetate, Isopropanol and Ethanol (above 50%). None of those solvents show any sign
of absorption.
Im sure the polymer can only absorb water due to the nature of the polymer, just wondering if anybody else had any info or suggestions.

Concerning the video:
As far as I know, calcium bicarbonate does not exist as a crystalline solid, it decomposes into calcium carbonate and carbon dioxide if you try to
crystallize it. This reminds me of an old occult recipe for a ring of invisibility, for which you need mercury that stays solid under normal
conditions, and long hair from a hyena.
Correct me if I'm wrong, but if I'm wrong, it isn't grocery store stuff anyway. This should be the marker that the author of the video is pulling your
leg.
