Call them maracas, chac-chacs, shakers, rattles, or tamaracas - there's no mistaking the percussive spice they add that makes Latin and Carribean music so special. Add the festive color-changing action found in these Light Shakers, and you will have an instant party! Light Shakers are designed with a special sensor with patent pending effect that allows them to glow brighter the harder you shake 'em, and the unique placement of the LEDs let you see the beads dancing inside. Use the "FUN" button to select solid colors of red, green, or blue; or switch to color change mode which alternates colors of the rainbow with every shake! - Ultra Bright Glow and Motion Activated Rattle
