~ Paint colorful, fun designs on the cardboard tube.
~ Cover one end of the tube with a couple of layers of aluminum foil, put a rubber band around it to hold it in place.
~ Fill tube with bird seed, un-popped popcorn, rice or beans.
~ Cover other end of the tube with several layers of aluminum foil and put a rubber band around it to hold it in place.
~ By gently turning the tube upside down and letting the objects in it fall and hit the aluminum foil the rainstick will simulate the sound of falling rain.
