I am a physicist, and I would like to work with those super nice "water pearls
" (ex : http://www.amazingwaterpearls.com/
). If I understood properlly, they are made of Sodium polyacrylate
The property that interests me as a physicist, is that I can work with spherical objects
nearly invisible in water. The only thing I would like to do is being able to change the radius
of those little spheres. In my dreams, I would like to be able to manipulate those spheres when they are dry (diameter of about 1mm) as if I was manipulating playdough. In this case I could change the radius of the final sphere (once full of water), and eventually insert some small particles in those spheres before wetting them.
So I purchased some of these and I could not find a way to manipulate them... (I tried to warm them up but they are still very rigid)
The questions I have for you are:
1- Is this possible? (I guess it has to be! The manufacturers of those "water pearls" are doing it!
2- How can I do it??
That would help me tremendously!!
Thanks a lot in advance!
PS: I hope I am in the good subsection of the forum... If not, I apologize... And I would blame my poor knowledge in Chemistry (as a Physicist
