Giant visual effect kit uses 98 bright red LEDS to provide an “exploding atom” electronic display. Kit sequences from a small “nucleus” center to consecutive larger rings - then “shrinks” back to the center again. Absolutely incredible display for science exhibits, game rooms, art displays or any place where you need to attract attention. Kit requires longer assembly time than most of our kits due to the large number of components. Please don't attempt this kit unless you have built other kits.
