If the water is distilled, even more)
Put it in a sticky gel
Sodium propylene is a polymer, which means that it consists of a chain of the same unit (monomers).
The monomer of sodium propylene is: it is a very cool polymer--
Shake out the crystal in the new diaper (
Or buy crystal in the garden center)
Add water to them. Pretty amazing!
