Exciting kit electronically creates an exploding "firework" like display. Kit features 17 micro red LEDs, 7 green mini LEDs and 1 jumbo red LED. The circuit uses a 2 transistor multi-vibrator that alternates between the "rings" of LEDs, which cause a display like "sky rocket" type fireworks. Great attention getter in a darkened room. Attractive and makes an interesting intermediate project.
