Each member of the Patrol has a clear glass pop bottle that has been partly filled with colored water, each with a different color. Each bottle is filled to a different level so that the eight notes of an octave can be played by blowing over the top of the bottle. Each member also has a flashlight (used only for the skit, please) which he holds against the bottom of the bottle, making his face glow with the color in the bottle. Every time a Scout blows a note, he turns on his light. You should stick to simple tunes, like Three Blind Mice, unless you are a musical group. However, it is great fun and a great effect, even if you "mess up" the music - after all, you gave it your best. It is also very effective (should you like) to have a conductor to lead the music, who has a flashlight with a colored cone on the front.
