When you hard boil an egg, molecular chemistry is at work. Eggs are made up mostly of two kinds of molecules: protein and water. The proteins in a raw egg are like twisted strings, floating in a watery soup. When you heat up an egg, the proteins break their bonds and unfold before making new, stronger chemical bonds between each other. When they’re still hot, though, the bonds between the proteins are moldable, kind of like clay. Try it out in this project and mold an abstract egg!
