We Built Working LEGO Siege Machines to Attack the Castle

Welcome to the Experimental Brick Unit channel! Watch a massive LEGO castle siege unfold as we test custom mechanical contraptions against a fortified stone fortress. Our engineering team pushes the limits of building blocks to create a series of siege engines and experimental machinery designed for maximum destruction. We focus on the physics of these custom LEGO builds, utilizing slow-motion cinematography to capture every gear turn, wheel spin, and impact within the wall defenses. This production highlights the professional setup required to safely operate high-stress models in a controlled environment. Whether you are interested in complex engineering or just want to see how these LEGO Technic experiments perform under real-world resistance, this footage breaks down the mechanics behind the chaos. We analyze the effectiveness of each experimental device, documenting how they operate when tasked with breaching a wall. ⏱ Video Chapters: 0:00 - In this video 0:24 - Viewing the targets 0:34 - Autonomous Ballista 2:20 - 4-wheeled Catapult 4:07 - Trebuchet 5:54 - Rammer 8:38 - Bringing down the walls 9:03 - Adding TNT dispenser modification 10:06 - Behind the scenes and Fails.
