Two cardboard tubes: One large mailing tube for
a poster about 24 inches long. Leave one of the
white covers in the end. The other cardboard tube
is from wrapping paper. It's about 28 inches long.
The hole is about 1 and 1/2 half inches. Paint with
white paint and a brush.
- Put the white cover in one end of the big
- Put the longer and smaller tube inside the
- Paint the outside of the bigger tube.
How it makes sound:
You hold the bigger tube so the white cover is
on the floor and hold the tube so that it is
vertical to the floor. You grab the inside tube and
move it up and down to make a sound. It bounces
against the white cover and the sound resonates
inside the tube.
Pitch and Volume:
You can't change the pitch, only the
volume. You can change the volume by hitting or
dropping the inside tub harder or softer.
