The cool hand-held Wobble Bopper Wand creates an impressive orb of multi-color rainbow light. Just wiggle the Wobble Bopper in your hand and the flexible stem will bounce around producing a trail of continuous colors. The Wobble Bopper utilizes an RGB high-frequency chip inside the "ping pong" ball on the end of a wiggly-jiggly spring. Just by moving the wand around, you can create huge orbs of light as you dance. The handle of the wand contains a built-in speaker that plays a repeating cute Asian-sounding dance song whenever the light is activated. The Wobble Bopper is approx. 14" long with a 1.5" diameter ball tip. The plastic body of the wand comes in assorted colors (no individual choice of color). Uses 3 replaceable AAA batteries (included).
