Orbeez are wet and wacky, soft and squishy, fun and funky, bouncy and beautiful. They start off hard and tiny. Add water and watch them grow to more than 100 times their volume. Grow your Orbeez and then fill your Flower shape to create a real-working designer lamp. With built-in LEDS and a choice of colors your flower will illuminate your room in a colorful light display. Requires 3AAA batteries, NOT included.
