How does gelatin become a solid?

What is the science behind Jello?

What makes gelatin gel?
The collagen is then dried, ground into a powder, and sifted to make gelatin. Heating breaks the bonds that hold the collagen together. When the mixture cools, the collagen strands reform into a semi-solid state with water molecules trapped inside. This is what gives jello its characteristic jiggly, gel-like texture.
