The magic ball is made of a substance called Sodium Poly Acrylate. It absorbs water, its molecular structure is such that water gets stuck in the middle of its structure. In addition to magic balls, this chemical is used in diapers and sanitary pads. It can absorb 800-1000 times its own weight Absorption has to be done through a semi-permeable screen, there is no screen, it is straightened.
These magic balls (SAP) which has the ability to retain water, so it swells by absorbing water. Observing these, I go somewhere for a while and go through the tub of the tree. It doesn't have any problem even if I don't water it for several days and Divya survives by extracting water from the soil, trees and from here.
But it was heard about the magic ball that it is dangerous for children. So it is wise for everyone to be aware.
