When you boil an egg, molecular chemistry is doing its work. Eggs are made up of two kinds of molecules: protein and water. 

When the boiled egg cools down, the proteins settle and its bonds solidify to form the shape of a rubbery egg. When it's still hot, the bonds between the proteins are moldable. That is why when you place a hot hard-boiled egg into a square box, it comes out in a cubic form!
