Burning steel. A piece of steel wool, burning in a pure oxygen atmosphere. Steel wool is made from tightly-bundled fine steel wire. Most metals when produced as very fine wire will burn, but many need to be bundled to produced a sustained flame. Steel burns very weakly in air, but quite spectacularly in pure oxygen.
