Rainsticks are so much fun. Tip one end up and listen to the sound of rain coming from within the stick! It's magic from nature. Filled with seeds, they make their way from one end to the other with a swoosh that sounds like falling rain. I knew a teacher who used one to get his class' attention. When they heard the stick, they had until the "rain" stopped to get quiet and to their desk. Brilliant!
Our Rainstick is about 14" long and has a string band on it. Diameters vary. Fun for ages 3 and up. Peru.
