Brass Hot Rod

Display a rod with six different colored dots on both sides. The spectator names a number between 1 and 6. Count to that color (blue for example). Give a quick shake and all the dots turn blue. Want to try again? Shake the dots back to their multicolored beginning. Choose another number, counting once again. Another shake and all the dots change red! May be handed out for examination.
