Gel - Wikipedia
WebA gel is in essence the mixture of a polymer network and a solvent phase. Upon stretching, the network crosslinks are moved further apart from each other. Due to the polymer strands between crosslinks act as entropic springs, gels demonstrate elasticity like rubber (which is just a polymer network, without solvent).

However, most of the mass of a gel is liquid, so gels can flow from application of relatively low stress.
