    • Using a brush gently brush away any excess powder, being careful to leave the exposed fingerprints intact.
    • Place a piece of scotch tape on top of the powdery print, then lift the tape (the fingerprint should have stuck to it. Place the scotch tape onto a piece of black construction paper to see it more clearly.
