Bric: structures combines the best of snap circuits with ordinary building bricks to create endless combinations of construction and circuitry! With patent-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 can energize their brick building experience with snap circuits and build innovative structures! Instead of just building a structure, now children 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! Our award-winning snap circuits products teach kids to have fun learning electricity, engineering, circuitry and more. Snap circuits features building components with snaps to assemble electronic circuits that function like the printed circuit board found in most electronic products. Snap circuits bric: structures includes: 20 snap circuits component parts, 75 bric-2-snap adapters, over 140 fully compatible building bricks, and a full-color, easy-to-read project manual.
