Turbo Sparkler Yo-Yo

This yo-yo uses holographic diffraction foil and flexible aerodynamic fins to produce a brilliant show of color and sound as it changes shape. Try spinning it in direct sunlight or another bright light source to create a fantastic visual effect. This is an excellent gift, and is also great for optics lessons in the science classroom!
