The Turbo Sparkler by Damert, is a unique novelty yo-yo patented by Bill Halon in 1989. In the first 10 years of the yo-yo's producion, over 500,000 yo-yos were sold, and due to this popularity, knock-offs were produced by other companies. Upon the threatening of legal action, the competitors' yo-yos were withdrawn from the market. The Turbo Sparkler is a variant of the Night Roller that features a series of holographic fins from the sides that bend to form a flared shape as the yo-yo spins, while producing a color-changing visual effect.
