- Put one of these caps on the end of any boomwhacker tube and hey presto - you've lowered the tone by an octave!
- Play the tubes as usual or hold them vertically and tap on the floor, etc., as a "stamping" tube
- Placed on the higher octave tubes they create the same tones as the bass octave tubes
- Placed on the bass octave tubes, they go down another octave, making a 3-octave range possible
