making your own water crystals?

thanks, a professor said they use it all the time for their cultures, so I though if they used it then i could to.
Hi,

Here is the way i look at it.

Water Crystals : polymer (Cross linked Polyacrylamide)

Agar : Freeze dried seaweed

Gelatin : meat by-products

They all seem to work for me in varies applications. I have found no way to make water crystals, yet.

Regards ;)
