YOU WILL NEED -

- A Tube Horn - Follow this Link to get instructions on how to build the Tube Horn, then come back here.

- Another tube that will fit inside your Tube Horn - it should be a snug fit but should be able to slide in and out easily.

PROCEDURE:

Slide the smaller tube into the bigger tube. The ideal is to slide smoothly in and out of the bigger tube without catching, yet be pretty snug to the side of the big tube.

If your smaller tube is too loose inside the big tube you lose the "trombone slide" effect. If the difference is not too much it is possible to wrap masking tape around the bottom end of the smaller tube to make a sort of gasket that prevents too much air from escaping (see below).

How to Play:

1. First, practice making your lips buzz. It's kind of like when you used to make machine gun sounds with your lips. Also you might consider the way that a horse does it (remember the old Mr. Ed shows?).

2. Press your lips up to the end of the smaller tube and buzz away!

HINT: With really short tubes (paper towel size, etc.) you can enhance the slide effect by buzzing your lips slightly faster when the slide is in and slightly slower as you pull the slide out.
