This three-minute timer features dual colored liquid going down in a Z-formation, creating a cool visual effect. Multi-colored droplets bounce down a staggered plane in the shape of a Z at the same time--see the droplets make their way down, only to reform again into a larger clump at the bottom. Makes an excellent desk toy, stocking stuffer, or unique timer for the classroom.
