Brixo Blocks
Usually, once you've assembled your latest masterpiece, it just collects dust on your shelf or becomes a plastic paper weight. But click in a few Brixo Blocks and get that Lego Back to the Future Time Machine hitting 88 MPH. Powered by a low voltage battery, these building blocks act as electric conductors to create simple circuits that add light, motion, and sound to any structure, without any annoying wires. A chrome coating makes them completely safe for the little ones, in case you decide to share.
