Insert the pointy end of a toothpick through one of the pin holes and press it into the tube as far as it will go. Blunt the ends of the toothpick sticking out of the tube by pressing them into the table or cutting them off with scissors. Put a toothpick in every hole. The more toothpicks you use, the more it will sound like rain. Pour the beans into the tube.
Smaller beans work better.
Cover the other end of the tube with plastic wrap and seal it with a rubber band. You can experiment with different size tubes and fillings like rice or other beans to change the sound.
