The Rainstick pictured here is a cactus plant turned inside out and then glued together.The spiny stickers are left inside for the seeds to hit as the stick is turned upside down to a vertical position, creating the sound of falling rain. The trick is to not let the sound be interrupted when all the seeds have fallen to one end of the stick. This is done by rolling the stick at a speed that still allows the seeds to make enough sound as it is turned upside down again. These sticks come in all sizes and are now also made from plastic.
