The Snap Together Circuits Light Show

This is the patented electronic circuit kit that lets young engineers quickly build engaging light displays. The kit's 60 parts can be easily assembled into 182 different projects, from a simple open-and-closed circuit to a shimmering, blinking light show using multicolored LEDs and a fiber optic tree. There's a sound-sensing module that flashes light in synch to the sound of a connected MP3 player or a child's voice. Each color-coded, numbered component snaps firmly to each other, making the illustrated instructions simple to follow and allowing for effortless experimentation. Includes DC motor and colorful "flying saucer" disk, jumper wires for more complex circuit designs, and audio cables to connect MP3 players. Requires four AA batteries. Ages 8 and up. Box 16 1/2" L x 12" W x 4 1/2" H. (3 lbs.)
