Building a Lego-Powered Submarine

As you know, I love me some Lego engineering builds. This one is pretty fun: using a large syringe, a Raspberry Pi, neodymium magnets, a controller scavenged from a toy submarine, and a bunch of Lego pieces, Brick Experiment Channel built a remote-controlled submarine. And it works so well! They even tested it by navigating 200 meters in a real stream.
