Make a Rain Stick

Cardboard tube (a paper towel roll is okay, but a long tube from gift-wrapping
paper is even better. You can also take two or three paper towel rolls and tape
them together.)
Materials:
What To Do:
1. Paper tubes have a spiral seam. Use a marker to draw dots about half an inch
apart, all the way down the spiral seam of the tube.
2. Poke a nail all the way in at each dot. (Make sure the nails don't poke through
the other side of the tube.) You'll need about 30 nails for each paper towel tube.
3. Wrap tape around the tube to hold the nails in place.
4. Cut two circles of paper just a little bigger than the ends of the tube. Tape one
of the circles over one end of the tube. Cover the circle with tape so the whole
end of the tube is sealed shut.
5. Put a handful of rice or beans into the open end of the tube. Cover the open
end with your hand, and turn the tube over. Add more rice or beans until you like
the sound. (Beans will make a harder sound, and rice will make a softer sound.)
6. Put the second circle of paper over the open end of the tube, and seal that end
shut with tape.
7. Your rain stick is complete. Turn it over and listen to the rain.
The rain stick is a musical instrument from South America. Traditionally, rain
sticks are made from the wood skeleton of a cactus. First, the thorns are pulled
off and pushed back through the soft flesh of the cactus. Then the cactus is left in
the sun to dry--with the thorns on the inside. Later, the hollow cactus is filled with
small pebbles, and the ends are sealed with pieces of wood.
