Jelly is a case of fluid in strong . 

A gel is a strong jam like material that can have properties extending from delicate and feeble to hard and intense. Gels are characterized as a considerably weaken cross-connected framework, which displays no stream when in the relentless state. By weight, gels are generally fluid, yet they carry on like solids because of a three-dimensional cross-connected system inside the fluid. It is the crosslinking inside the liquid that gives a gel its structure (hardness) and adds to the cement stick (tack). Along these lines gels are a scattering of atoms of a fluid inside a strong in which the strong is the nonstop stage and the fluid is the broken stage.
