Can gelatin be melted and reset?

Yes, gelatin can be melted and reset. Gelatin is a protein derived from collagen, which is found in the connective tissues of animals. When gelatin is heated in water, it dissolves and forms a gel when it cools. This is because the gelatin molecules absorb water and form a network of bonds that trap water molecules. The gel can be melted again by heating it, and it will reset when it cools. This process can be repeated multiple times.
