The mesmerizing motion inside any of these three sensory fidget tubes offers children a soothing visual distraction. Each tube focuses on a different sense - sound, sight and feel. Children can hear the beads as they fall down the spiral, they can watch the smiley faces swirl in the glittery water, and they can feel the weight of the sand as it falls downwards towards the textured end caps. Fidget tubes provide quiet, engaging play that helps to calm anxious or agitated children.
