The KidO Activity Board is perfect for learning cause and effect, action/reaction and early reasoning. Turn the dial and hear the heartbeat, control the volume by how you turn the dial. Slide the colored knobs to change the flower from red to blue to green; watch how the colors blend and create new colors as the knobs move! Feel how the yellow bee buzzes and lights up as you press the blue button as you control the intensity of the vibration. Bright colors and interesting shapes hold your child's attention, and an integrated handle makes it easy to grab and go.
