Description
                            These 16" tubes make two noises when tipped - a warbling noisemaker is inside and beads rattle down the spiral design. The spiral gravity tube is a great visual toy that also provides auditory input and feedback. It also helps children with the concept of cause and effect making it a great toy for kids with autism and other special needs.
