    Quizzical Pursuit
    —The Architecture Puzzler

    Created by Dave Guadagni

    Solution to Last Week's Puzzler
    Architecture Puzzler #317

    Question

    How does rust form?

    Answer

    When water and air contact bare ferrous metal, microscopic particles of iron (ions) go into solution and react chemically to form iron hydroxides and iron oxides know as rust.
