Dr. Frankenstein had to figure out how to harness a storm to bring his creation to life, but you can animate your LEGO builds with the LEGO Technic Power Functions Motor Set, $17 at Walmart and Amazon. It’s $20+ anywhere else, and it’s a fun upgrade for your existing LEGO Technic sets. (The super-STEM-minded might even be able to build original machines that work with it.)
