Tube Trombone

The tube trombone is similar to a real trombone because it is played by buzzing the lips and
 it has a form of a slide. Although the sound of the tube trombone isn't pleasant and 
melodic, it is fun to play with and a great introduction to brass-type instruments. 


 How to Make It 

To make your trombone, you will need two cardboard tubes, each about a foot long. One should
 be able to fit in another. I recommend using a paper towel tube and a wrapping paper tube.
 You will also need a pair of scissors and two rubber bands.

To start, cut the bigger tube straight across from one end to another. Place the smaller 
tube inside of it. Now fasten the rubber bands around the larger tube, making sure that the 
smaller tube can still move around inside of it. The fit shouldn't be too roomy. Look up at 
the above picture to see what your instrument should look like. To play, buzz your lips 
inside the larger tube. Move the smaller tube (the "slide") around to obtain different 
tones. Have fun!
