Kids can use their imagination to combine Snap Circuits® with ordinary building bricks and make endless combinations of construction and circuitry. With thepatent-pending, Bric-2-Snap technology, kids can wire up their brick builds with Snap Circuits® lights, sounds, moving parts and 3-D circuits to invent almost anything and make it go! Kids love to create and invent from what they have at home. Instead of just building a structure, now kids can learn how to build the circuit that makes the lights on a skyscraper illuminate or that makes the gears on a drawbridge move! Elenco’s team of engineers has come up with a great way for kids to Learn By Doing® and be creative with their everyday, building bricks. There’s no limit to what kids can create with Snap Circuits® BRIC: STRUCTURES!
