Our patented Rendezvous® Rainstick is second-loudest only to our Crystalline Beads Spiral Sounds® Rainsticks. The Rendezvous combines the sounds of both glass microbeads and amaranth. Both materials flow simultaneously for 3 minutes and then produce an echo effect in which the microbeads fade first, while the amaranth continues for another 20 seconds. A video of our most unique rainstick is in the product description.
